Question

Can anyone help ( math, geometry)

Answer 1

x=18

Explanation:

(3x-9)= 45 degrees because the angle you are solving for is half of a right angle (90 divided by 2 = 45)

so you take 45 and add 9 to it. That equals 54. To get the value of x, you divide 54 by 3 and you get 18.

hope this helps!
