Question

What is the value of x?

A) x = 32
B) x = 36
C) x = 37
D) x = 40

Answer 1

Step-by-step explanation:

x + (4x - 20) = 180

5x - 20 = 180

5x = 180 + 20

5x = 200

x = 200/5

x = 40°

Option → D

Answer 2

Answer:

$x = 40$

Answer D is correct

Step-by-step explanation:

Angles in a straight line is added up to 180°

Therefore,

$x + 4x - 20 = 180 \\ 5x - 20 = 180 \\ 5x = 180 + 20 \\ 5x = 200 \\ \frac{5x}{5} = \frac{200}{5} \\ x = 40 \degree$
