GH=JH
H1 = H2 (vertical angles)
FH=HI
so the triangles are congruent by SAS theorem
FGH=HIJ => FG=JI
good luck
So for this, you'll be using the pythagorean theorem to solve for the height.

Solve the exponents to get

Subtract 81 on each side to get

Square root each side, and your answer should be

or 13.23 ft

Answer:
x = 91, y = 89, z = 31 Fourth choice
Step-by-step explanation:
x = 180 - 51 - 38 = 91
y = 180 - 91 = 89
z = 180 - 60 - 89 = 31
