If AB ║ CD then <GEB = 50 (corresponding angles are equal)
Answer is B.
<GEB = 50
I believe the answer you are looking for is -20.
Hope you won't be turned off by a correction, but we really need to use the symbol " ^ " to denote exponentiation.
Thus, we have x^2 = 100
Taking the square root of both sides, we get x = plus or minus 10. Verify, please, that both x = -10 and x = +10 satisfy the given equation.
