Using Pythagorean's Theorem we know that a^2 + b^2 = c^2
C is the length of the ladder, and we are given one of the sides, let's call that side b
_________
we have a^2 + b^2 = c^2, and a^2 = c^2 - b^2, so a = √ c^2 - b^2
_________ ______ ____
a = √12^2-3^2 = √ 144-9 = √ 135 = 11.61895
so the top of the ladder is 11.6 feet above the ground
here u go hope this helps
Answer:
12 sin60°
Remember SOHCAHTOA.
sinθ =
opposite
hypotenuse
sin60° =
x
12
x = 12 sin60°
