A tree is leaning at a 5° angle from vertical, making an 85° angle with the ground. When the sun is at a 65° angle of elevation, the tree casts a 25-foot shadow. What is the approximate length of the tree?

The triangle is formed by the tree, its 25-foot shadow, and the sun’s ray. Its angles are 85° where the tree meets the ground and 65° where the ray meets the ground, so the third angle is 30°. By the sine rule, the tree’s length is 25 × sin(65°) ÷ sin(30°) ≈ 45 feet, so the correct choice is 45 ft.
