Answer:
I believe it's -27.25
Explanation:
so the angles of a triangle should all add up to 180 or any 2 angles on a line should add up to 180.
add the 30 and 106 to get 136
subtract 136 from 180 and get 44
(that part is unnecessary tbh)
(-4x+27)=136
subtract 27 from both sides to get -4x=109
divide 109 by -4 and you get -27.25
switch it with x to make sure its right
