180 degrees in a triangle
180-70-30 = 80
The other angle is 80 degrees

70+30 is 100
There are 180 degrees in a triangle so 180-100 is 80
The answer is 80

How much degrees does a square equal?
A Square Or A Quadrilateral Or A Polygon With Four Straight Sides Has 360 Degrees!!=] I Know This Is Not The Question But It Is Related] A Triangle Has 180 Degrees!!=)
How much should all sides of a triangle equal up to?
There are four types of triangles. For an "equilateral triangle", all sides and angles have to be the same. For an "isosceles triangle", 2 of 3 sides and angles have to be the same. For a "scalene triangle", the "the same" rules don't apply. For a "right-angled triangle", one corner has to be a right angle (90 degrees.) For example in an equilateral triangle, as long as the sides are the same, they can add up to anything. However, angles are different. In any given triangle, the angles must add up to 180 degrees.
How do you know the other 2 angles if only 1 angle is given?
you work out how much it is to 180
How much does and acute angle measure?
what is the measurement of an acute angle
If a triangle has 90 on one side and 90 on the other how long is the third side?
if it is a triangle then it could be pretty much anything depending on the angles, and if your talking about angles then the third angle would be zero because they add up to 180 degrees.or you could use a squared plus b squared = c squared if the two nineties are the small side. Then c would = the square root of 16200 which is too hard for me to figure out right now.
If I have the height and another measurement of a triangle how do I find the base?
Regardless of whether the "other measurement" is an angle or the length of something, that much information is never enough to define anything else about the triangle.
What is the answer if you have 70 degrees and 30 degrees in a triangle but you need to find out how much the other angle is?
The inner angles of a triangle add up to 180 degrees. 180 - (70 + 30) = 80 degrees.
How much degrees is a right angle triangle?
The angles of a triangle always add up to 180o. A right angle triangle has angle of 90o, 60o, 60o.
How do you find the missing angle in a triangle if you are given the other 2?
easy a triangle makes up a total of 180 degrees so add the two up and then see how much more is needed for 180 and there's your answer
What combinations of sides and angles can you use to tell the rest of the information for a triangle?
To find all the other information of a triangle, you would need the information of an SAS (Side Angle Side, in that order), an ASA (Angle Side Angle), or a SSS (Side Side Side). Only triangles shown with this much information can be solved, other than that, you just can't be sure of the rest of the measures of the sides and angles.
How do you Calculate the right angle of a triangle?
Al you need to get is a protractor to measure it really. say you had a straight line you know how much that measures and you know how much the other angle measures so subtract it and you have the answer!
How much is The angle of isosceles Triangle?
There could be almost any acute angle. it maters what kind it is
How much is each angle in a triangle?
It depends on the triangle, whether it's an isoscelese, scalene, equlateral, obtuse, right angle or acute triangle. All the angles have to add up to 180 degres no matter what, so a right angle triangle could be 90, 45 and 45.
How much does a triangle mesure?
180 degrees. An equilateral triangle measures 60 degrees at every angle.
How much degrees does an equilateral triangle have?
Total, the triangle has 180 degrees, and each angle has 60 degrees.
How much equal sides does a equilateral triangle have?
A triangle always has three sides, thus the name tri-angle (3 angles)
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
