Since the internal angles of a triangle always add up to 180...
180=5x+3x+x is the same as 180=9x - therefore 180 divided by 9 equals 20.
The three angles are 100, 60 and 20 degrees respectively.

How many acute angle in the letter A is?
Three, forming the triangle above the line. The two angles below the line are obtuse.
Why can a triangle have three acute angles?
YES!!! The types of triangle and their angles. Equilateral ; all 60 degrees ; acute. Isosceles; All three acute angles, or two acute angles and one obtuse angle. Right angles ; One 90 degree angle and two acute angles. Scalene ; All three acute , or two acute and one obtuse. NB There are no such triangles with two or three obtuse angles.
What does isosceles triangle look like?
An isosceles triangle has at least two equal sides and two equal angles An isosceles triangle has two or more congruent sides called legs. In an isosceles triangle with just two congruent sides, the angle formed by the legs is called the apex, and the other two angles, called base angles, are congruent. If the isosceles triangle has three congruent sides (AKA an equilateral triangle), then all three sides and angles are congruent, and there are no definitive base or vertex angles, besides...all of them.

What is a acute trianlge?
an acute triangle is a triangle that has corner angles all below 90 degrees. there are three types of triangles: obtuse, right, and acute. obtuse triangles have one corner angle greater than 90 degrees, right triangles have one angle equal to 90 degrees, and acute triangles have all corner angles less than 90 degrees.
What degree of angle for octagon?
For a Regular Shape (all angles measure the same), you can split it up into triangles to find the total angle measures. For example, in a square, you can only split it in half, making 2 triangles (below). A triangle always measures 180 degrees, so for an octagon you would split it into triangles from one point. If you count the triangles, you will have 8 triangles. Now Multiple 8 by i80, and your sum of angles will be 1080°.If you then divide it by the sum of the angles in a triangle, or 180 degrees, you will find that 1 angle measures 135 degrees. This rule applies to all Regular Polygons. If you still don't get it,try the link below
Determine the measure of the missing angle in the triangle below the sum of the three angles in a triangle is 180 degree?
37 degree
How many degrees do the 3 angles in a triangle add up to?
The 3 angles in a triangle ALWAYS add up to 180 degrees. Below are the different types of triangles: * Right triangle: one 90 degree angle * Equilateral triangle: All angles are the same (60 degrees) * Isosceles triangle: two angles are the same and two sides are the same * Scalene triangle: all three angles and all three sides are different * Obtuse triangle: one obtuse angle (angle greater than 90 degrees)
Exterior angle of a triangle?
Exterior Angle Theorem Exterior angle of a triangle An exterior angle of a triangle is the angle formed by a side of the triangle and the extension of an adjacent side. In other words, it is the angle that is formed when you extend one of the sides of the triangle to create a new line, and then measure the angle between that new line and the adjacent side of the original triangle. Each triangle has three exterior angles, one at each vertex of the triangle. The measure of each exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it. This is known as the Exterior Angle Theorem. For example, in the triangle below, the exterior angle at vertex C is equal to the sum of the measures of angles A and B So, angle ACB (the exterior angle at vertex C) is equal to the sum of angles A and B.

How many acute angle in the letter A is?
Three, forming the triangle above the line. The two angles below the line are obtuse.
Which shape fits the description below A three-sided figure with one acute angle one right angle and one obtuse angle.?
A three sided shape is a triangle but the given angles are incorrect because a triangle can't possibly have a right angle and an obtuse angle because its 3 interior angles must add up to 180 degrees.
What is the measure of the largest angle in an obtuse triangle?
178 degrees is the largest angle for an obtuse angle because 180 is a straight angle and 90 degrees is an right angle and below 90 degrees is an acute angle. Some supposedly say that the answer is 179,But it's not! the reason behind this is because in a triangle all the angles have to add up to 180 degrees. There are 3 points to a triangle so there has to be 2 extra degrees taken off of 180, which equals to 178. Explanation is terms: angle A + angle B + angle C = 180 degrees [Sum of supplementary angles of a triangle] 178 degrees + 1 degree + 1 degree = 180 degrees which makes sense. I figured this out when i was doing homework... Hope this helps you other people

Can there be a triangle with all angles below 1?
yes
If one angle of a triangle measures what is the measure of the third angle?
The sum of the three angles of a triangle is 180 degreesIf it is a right angle triangle one angle must be 90 degreesAll u have to do is 180-90- (the angle u already know)= unknown angle (third angle)Just like regular numbers, angles can be added to obtain a sum. Sometimes we can determine a missing angle because we know that the sum must be a certain value. Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees.If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry. We can use this idea to find the measure of angle(s) where the degree measure is missing or not given.Sample AIn triangle ABC below, angle A = 40 degrees and angle B = 60 degrees. What is the measure of angle C?We know that the sum of the measures of any triangle is 180 degrees. Using the fact that angle A + angle B + angle C = 180 degrees, we can find the measure of angle C.angle A = 40angle B = 60angle C = we don't know.To find angle C, we simply plug into the formula above and solve for C.A + B + C = 180C = 180 - A - BC = 180 - 40 - 60C = 80To check if 80 degrees is correct, let's add all three angle measures. If we get 180 degrees, then our answer for angle C is right.Here we go:40 + 60 + 80 = 180180 = 180...It checks!You don't always have to plug in those values to the equation and solve. Once you're comfortable with this sort of problem you'll be able to say "okay, 40 + 60 =100, so the other angle has to be 80!" and it's much quicker.Sample BIf a triangle is equiangular, what is the degree measure of each of its angles?Remember, all angles of an equiangular triangle have equal measure. Let x = the degree measure of each angle. Triangles have three vertices and so we will add x THREE times.We have this:x + x + x = 1803x = 180x = 60Makes sense, right? If all the angles are equal, and they add up to 180, then it has to be 60 degrees!NOT USFULL TO LONG BIA
