-3x-6=-4x-9
x - 6 = -9
x = -3
y = -3(-3)-6= 9 - 6 = 3
Two intersecting lines will form 2 pairs of congruent vertical angles. Congruent angles have the same angle measure; vertical angles are opposite angles formed by 2 intersecting lines.
Corresponding sides on either side of ED are proprotional, so
(x+2)/112 = 62/99.2
x +2 = 112*62/99.2 = 70
x = 68 feet
