Question

the measures of the two angles of a triangle are 100° and 50° . Find the measure of the third angle​

Answer 1

Answer:

Step-by-step explanation:

The sum of all angles of a triangle is 180°.

Let a triangle ABC such that A= 35°, B= 45°

A+B+C = 180°

35° + 45° + C = 180°

80° + C = 180°

C = 180° - 80°

C = 100°

So, the measure of third angle is 100°
