Answer:
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 !
