Question

Two angles of triangle are 45 degree and 55 degree. find the measure of third angle​

Answer 1

Answer:

80 is the correct option the third angle isthe 80 degree

Answer 2

Given:

Two angles of a triangle are 45° and 55°

To find:

The measure of the third angle

Calculation:

The sum of angles in a triangle is 180°

=> Sum of angles = 180°

=> 55° + 45° + x = 180°

=> 100° + x = 180°

=> x = 180° - 100°

=> x = 80°

The measure of the third angle is 80°
