X is side to side and Y is up and down. Hope this helps.
Area of a triangle = 1/2 x base x height.
Replace are and base to get:
82.5 = 1/2 x 15 x height
Multiply both sides by 2:
165 = 15 x height
Divide both sides by 15:
Height = 165 / 15
Height = 11 inches.
Let angle ladder makes with the ground be x degrees.
sin x = 11.8/12
x = sin^-1(11.8/12)
x = 79.5 degrees (3 s.f.)
yes it is possible
