Question

If the two angels of a triangle are 40° and 50° find the measure of third angel​

Answer 1

Answer: 90˚

Step-by-step explanation:

A triangle has angles that add up to 180˚. If we have two angles already, we can find the third one by subtracting the known angles. 180-40-50=90˚

Answer 2

Answer:

2 angles of the triangle = 40° and 50°

therefore, the sum of 2 angles = 90°

Sum of the 3 angles of triangle = 180°

therefore, the 3rd side = 180° - 90°

= 90°
