Question

Find the value of x

A. 108
B. 72
C. 27
D. 45

Answer 1

c

Explanation:

This shape is made from a four sided shape which is 360°

and a three sided shape which is 180°

so the combined interior degrees is 540°

so

3x + 6x+ 1 + 2x + 4x + 5x-1 = 540

20x = 540 combine like terms

/20 /20

x = 27
