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

Step-by-step explanation:

Step 1: Identify Variables

Leg a = 8

Leg b = x

Hypotenuse c = 10

Step 2: Solve for x

  1. Substitute [PT]:                    8² + x² = 10²
  2. Isolate x term:                      x² = 10² - 8²
  3. Exponents:                           x² = 100 - 64
  4. Subtract:                               x² = 36
  5. Isolate x:                               x = 6

Answer:

x=6

Step-by-step explanation:

According to Pythagoras theorem

x²+y²=z²

x²+8²=10²

x=√10²-8²

x=√100-64

x=√36

x=6
