A triangle has 180 degrees.A right triangle has exactly one angle measuring 90 degrees.If you know that one of the other angles of the triangle is 20 then your third angle is:180-90-20 = 70 degrees.


One acute angle of a right triangle measures 20 degrees what is the measure of the other acute angle?

70 degreesA right triangle has a right angle that measures 90 degrees, and the total number of degrees in a triangle is 180 degrees.180 - 90 leaves 90 for the other two, and 90 - 20 = 70

Vertex angle A of isosceles triangle ABC measures 20 degrees more than three times measure of angle B Find angle C?

The vertex angle of an isosceles triangle is the angle opposite the base of the triangle. Therefore, the other two remaining angles of the triangle are congruent. so, in this problem: Let x = m of angle B Let x1 = m of angle C Let 3x + 20 = m of angle A x + x + 3x + 20 = 180 5x + 20 = 180 5x = 160 x = 32 degrees Since angle B and C are congruent, the measure of angle C = 32 degrees.

Must a triangle with two acute angles be a right angle?

No. For example, say the two angles are 10° and 20°. Then the other angle is 180°-10°-20°=150° and that is not a right angle. But if the triangle has two equal acute angles of 45 degrees then the 3rd angle must be 90 degrees which will form a right angle triangle.
