Question

What is the solution and how do I solve this step by step?

Answer 1

Exterior angle theorem: The sum of the exterior angle = the sum of two non-adjacent interior opposite angles

So we can say that…

16x + 8 = 60 + 4x + 8
-8
16x = 60 + 4x
-4x
12x = 60
/12
x = 5

Answer: x = 5

Have a good day ^^
