Question

if 2 X degree is the exterior angle of triangle and x degree and 45 degree are opposite interior angle find the value of x degree​

Answer 1

45 degrees.

Explanation:

The exterior angle = sum of the 2 opposite interior angles.

2x = x + 45

2x - x = 45

x = 45.

Answer 2

x = 45 degrees

Explanation:

The measure of exterior angles is equal to the sum of non-adjacent interior angles

=> 2x = x+45

=> 2x-x = 45

=> x = 45 degrees
