Best Answer

180-(90+40) = 180-130 = 50 degrees

JustinBeiberCute:

That is the right answer. i just thought 50 because there is 90 degrees in 1 angle. If you have 40... there if 50 degrees left.

90

- 40

The sum of the measure of two angles of a triangle is 95 degrees What is the measure of the third angle?

The third angle is 85 degrees. The sum of all internal angles in a triangle is always 180 degrees


The measure of an exterior angle of a triangle is120 degrees the interior angles that are not adjacent to this exterior angle are congruent find the measure of the interior angles of the triangle?

They are all 60 degrees.


How do you classify a triangle by its angles?

If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)


Two angles in a triangle measure 48.3 degrees and 33.6 degrees. What is the measure of the third angle in the triangle?

The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1


If two angles of a triangle each measure 45 degrees what is the third angle?

If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.


Two angles of a triangle measure 45 degrees and 60 degrees what is the measure of the third angle?

The third angle is 75 degrees. The 3 angles of a triangle add up to 180 degrees. Therefore: 45 + 60 + 75 = 180.


What is the measure of the third angle of a right triangle if one of the angles measures 50 degrees?

The other acute angle in that triangle is 40 degrees.


Two angles of a triangle each measure 70 what is the measure of the third angle in degree?

The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.


Two angles of a triangle measure seventy four degrees and forty one degrees. What is the measure of the missing angle?

Since the sum of the internal angles of a plane triangle is 180 degrees, the measure of the missing angle is 65 degrees. 180 - 74 - 41 = 65 degrees.


The measure in a third angle in a triangle with angle in a triangle with angles of 39 and 77 degrees is.?

180-39-77 = 64 degrees

What is the measure of the third angle of the triangle if the measures of two angles of a triangle are 35deg and 45deg?

The missing angle measure is 100 degrees.


What would the exterior angle of a triangle measuring 75 degrees be?

A triangle can't measure 75 degrees. A measure in degrees applies to angles, not to polygons such as triangles. In a triangle on a flat surface, the sum of angles is 180°.


What is the measure of the base angles of an isosceles triangle whose vertex angle has a measure of 50 degrees?

130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.


What is the sum of the acute angle measure of a right angle?

The sum of the angles of a triangle is 180 degrees. A right angle is 90 degrees. So the sum of the remaining two acute angles of a right triangle is 90 degrees.


What is the measure of the base angle of an isosceles triangle if the measure of the vertex angle is 42 degrees and the two congruent sides each measure 21 units?

If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees


If 2 angles of a triangle measure 110 degrees and 43 degrees what is the measure of the remaining angle?

The 3 angles of a triangle always add up to 180 degrees. You have 110 and 43, so that is 153 degrees. Subtract 153 from 180, and that is the remaining angle.


If Two angles of a triangle each measure seventy degrees what is the measure of the third angle in degrees?

The three angles always add to 180, so the third angle would be 40 degrees.


In a right triangle there is a 57 degrees angle. What is the measure if the third angle?

The angles are 90 degrees, 57 degrees and the third angle is 33 degrees


Can one angle in a right triangle measure 100 degrees?

No, because a triangle's angles can only measure up to 180 degrees. A right angle is 90 degrees, plus another 100 degree angle would be 190 degrees.


If two angles of a triangle each measure 54 degrees what is the measure of the third angle?

The 3rd angle must be 72 degrees because the 3 angles in any triangle add up to 180 degrees and so 54+54+72 = 180 degrees


What is the measure of an isosceles triangle in which the measure of the vertex angle is twice the measure of one of the base angles?

The 3 interior angles are 90 degrees, 45 degrees and 45 degrees


Two angles in a triangle are 35 degrees and 60 degrees what is the measure of the third angle?

85 the three angles of a triangle should add up to 180 degrees


In a triangle the measure of the first angle is 24 degrees more than the measure of the second angle. The measure of the third angle is four times the measure of the second angle. If the total number?

The angles in the triangle work out as 50 degrees, 26 degrees and 104 degrees which all add up to 180 degrees.


What is the measure of base angle if vertex angle of an isosceles triangle is 80?

The base angles will have equal angles of 50 degrees
