Question

- If the exterior angle of the triangle measure 133°, and its remote interior

angles measure x° and (2x-5)°, what is the value of x?

a. x = 61.7°
b. x = 133°
c. x = 47°
d. x = 46°

Answer 1

D

Explanation:

Mathematically;

the exterior angle is the sum of the two remote interior angles

Thus;

x + 2x-5 = 133

3x-5 = 133

3x = 133 + 5

3x = 138

x = 138/3

x = 46
