Aladder 40 feet in length rests against a vertical wall. the foot of the ladder is 7 feet from the wall. what angle, θ, does the ladder make with the ground? (round angle measure to the nearest degree.)

The ladder makes 79.92 degrees of angle with the ground (Calculation: Cos A = 7/40 = 0.175 resulting A = ACos 0.175 = 79.92 degrees). This problem can be solved by using a simple trigonometry formula of Cosine which stated Cos A = Adjacent/Hypotenuse. The ladder length of 40 feet is the hypotenuse side of the triangle and the 7 feet distance between the ladder's foot and the wall is the adjacent side.

Heptagon is the correct ans

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
