Question

Calculate the value of x

Answer 1

x = 52°

Explanation:

the angle of 172° is the angle opposite to x + 16 + 2x, so x + 16 + 2x = 172, we solve for x

x + 16 + 2x = 172

3x = 172 - 16

3x = 156

x = 156 : 3

x = 52°

-------------------------------

check

52 + 16 + 2(52) = 172

172 = 172
