Question

What is the value of x?
х= 32
х= 36
х = 37
x= 40

Answer 1

x = 40 deg

Explanation:

Given that the line at the base of the triangle is a continuous straight line,

x + (4x-20) = 180 degrees

x + 4x - 20 = 180

5x = 180 + 20

5x = 200

x = 40 deg

Answer 2

The answer is 40 because 5x=200 and so X must equal 40
