Question

What is the value of x

Answer 1

Answer:

x=40

Step-by-step explanation:

if you add the angle with a value of (x) to the angle with a value of (4x - 20) the sum will be equal to 180 degrees because a straight line is created with the sum of the two angles. A straight line is basically just an angle with a value of 180 degrees.

x+(4x-20)=180

5x-20=180

5x=200

x=40
