A 12 foot ladder leans against a building so the angle between the ground and the ladder is 72∘. How high will the ladder reach? Round your answer to the nearest tenth, and do not include "x=" or any units in your answer. Just enter a numerical value.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

80 the answer is 80
