Trigonometry

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

• a is a leg
• b is another leg
• c is the hypotenuse

Explanation:

Step 1: Identify

Leg a = 35

Leg b = 12

Hypotenuse c

Step 2: Solve for c

1. Substitute in variables [Pythagorean Theorem]: 35² + 12² = c²
2. [Hypotenuse] Rewrite: c² = 12² + 35²
3. [Hypotenuse] Evaluate exponents: c² = 144 + 1225
4. [Hypotenuse] Add: c² = 1369
5. [Hypotenuse] [Equality Property] Square root both sides: c = 37
