Question

A 25-foot ladder leans against a house. The bottom of the ladder is 7 feet from the house.

To the nearest degree, what angle does the ladder make with the ground?

Answer 1

Answer: it makes 74 degree

Explanation: This forms a right triangle. The 25-ft ladder is the hypotenuse of the right triangle. and the 7ft bottom of the ladder is the base of a triangle

For the angle where the ladder meets the ground, the

ground is the adjacent leg. The ladder is the hypotenuse.

Call the angle between the ladder and the ground angle A.

The trig ratio that relates the adjacent leg and the hypotenuse is cosine.
