A 20 -ft ladder leans against a building so that the angle between the ground and the ladder is 84 ∘ . How high does the ladder reach on the building?

Question

Round answer to 2 decimal places as needed.

Its a right triangle with the hypotenuse of 20. The angle is 84. 20 x sin84 = 19.89.

That is the length of the leg opposite the 84 deg angle and also how for it goes up the wall
