Trigonometry questions and answers. A 37-foot ladder is leaning against the side of a building. The angle of elevation of a ladder leaning against a wall = 45° The foot of the ladder away from the wall = 8 m. Formula: cos θ = Base/Hypotenuse. Calculation: From the following figure. AC is ladder. BC = 8 m. In ΔABC. ⇒ cos 45°=BC/AC. ⇒ 1/√2 = 8/AC. ⇒ AC = 8 √2. ⇒ AC = 8 × 1.414. ⇒ AC = 11.31. ∴ Length of the ladder is 11 ....

This requires Pythagoras' theorem which says that the square of the hypotenuse = square of another side + the square of another side. Therefore, a² = b² + c² where a is the length of the ladder, and b and c are the wall and floor. If the ladder is 13 feet long, and the bottom of the ladder is 5 feet long then: 13² = 5² + c².
