If line DE is perpendicular to line HK, that means angle KHE is a right angle. Also, since angles GHE, KHE, and KHA are all on line AHG, those three angles should be supplementary. Therefore, we can set up the following equation:
(60 - x) + (2x - 6) + 90 = 180
x + 54 = 90
x = 36
Therefore, choice B is the value of x and Jeb’s answer is wrong.
Hope this helps!
