Question

The exterior angles of a triangle measure x°, (2x)°, and (3x)°. What is the value of x?

A. 60

B. 72

C. 30

D. 45

Answer 1

Option A 60°

Explanation:

we know that

The sum of the exterior angles of a polygon must be equal to 360 degrees

so

In this problem

(x+2x+3x)=360°

6x=360°

x=60 degrees
