Question

What is the value of x

Group of answer choices

60 degrees

30 degrees

15 degrees

45 degrees

Answer 1

x = 15 degrees

Explanation:

This is a right angle, since we know that a right angle contains 90 degrees, we can form an equation.

`30+4x=90`

Now, we solve for x.

`-30+30+ 4x = -30+90`

`4x=60`

`(4x)/(4)=(90)/(4)`

`x=15`
