Question

Find the value of this variable

A. 146 degree
B. 73 degree
C. 84 degree
D. 62 degree

Help!!!

Answer 1

Answer: B. 73 degree

Explanation:

We know that a triangle has 180 degree

62 + 84 = 146 degree

180 - 146 = 34 degree

34 degrees is the angle inside the triangle. The inside angle must add with the outside angle = 180 degree

So the outside angle is

2x = 146

x = 73
