300

A tree casts a shadow that is 15 feet long. The angle of elevation from the tip of the shadow to the top of the tree is 35°.

Use tan(35°) = height / 15
→ height ≈ 15 × tan(35°)
→ height ≈ 15 × 0.700
→ ≈ 10.5 feet

400

A kayak is anchored 20 feet from a riverbank. The rope connecting the kayak to a tree on the bank forms a 42° angle with the water.
Using sine, find how high up the tree the rope is tied.

Use sin(42°) = height / 20
→ height ≈ 20 × sin(42°)
→ height ≈ 20 × 0.6691
→ ≈ 13.38 feet

A plane takes off at a 30° angle and has traveled 300 meters along its flight path.
Using cosine, how far above the ground is the plane horizontally from where it started (horizontal distance)?

Use cos(30°) = horizontal distance / 300
→ horizontal distance ≈ 300 × cos(30°)
→ ≈ 300 × 0.866
→ ≈ 259.8 meters
