Need some heeell
lines a and b are parallel

The value of x is = to 5

Step-by-step explanation:

There are multiple ways to solve this problem,

The way I solved it was by looking at 11x and noticing that it has a vertical angle which would give you the third angle in the triangle formed.

In the triangle you then have 90, 11x, and 7x.

A triangle must always = to 180 so set the equation 7x + 11x + 90 = 180

Then solve for x, 18x + 90 = 180

                              18x -90  = -90

18x = 90

90 /18 = 5 Therefore x = 5

Your answer is the first option or choice A. Your Welcome, My pleasure !
