Question

Measure of two angles in a triangle are 70° and 45° find the third angle

Answer 1

Let, 70 degree= angle A
45 degree= angle B


Third angle be C

Therefore,
angle A + angle B + angle C =180 degree...............[Sum of angles of triangle is 180]

70 + 45 + angle C = 180

155+ angle C = 180

angle C = 180 - 115

Therefore, angle C = 65 degree
