Solved Right Triangle Trig Review Warm Up - What Is | Chegg.com - Free Printable

- sin θ = Opposite / Hypotenuse
- cos θ = Adjacent / Hypotenuse
- tan θ = Opposite / Adjacent

Example 1:
- sin A = 8/17
- cos A = 15/17
- tan A = 8/15
- sin B = 15/17
- cos B = 8/17
- tan B = 15/8

Example 2:
1. x = 7 * sin(70°) ≈ 6.58
2. x = 10 / tan(65°) ≈ 4.66
3. x = 4 / sin(24°) ≈ 9.83
4. x = 20 * sin(55°) ≈ 16.38

Example 3:
- To find a missing angle in a right triangle, we must use inverse trigonometry.
- sin⁻¹(0.5) = 30°

Finding the ? angle:
1. ? = sin⁻¹(6/8) ≈ 49°
2. ? = cos⁻¹(4/5) ≈ 37°
3. ? = tan⁻¹(14/48) ≈ 16°
4. ? = sin⁻¹(16/34) ≈ 28°
5. ? = cos⁻¹(51/85) ≈ 53°
