Answer:

Explanation:

These questions all use Pythagorean Theorem to solve for x.

The hypotenuse is the side across from the right angle.

It is always c in the equation.

10) a² + b² = c²

x² + 9² = 15²

x² + 81 = 225

x² + 81 - 81 = 225 - 81

x² = 144

√x² = √144

x = 12

11. a² + b² = c²

x² + 2² = 5²

x² + 4 = 25

x² + 4 - 4 = 25 - 4

x² = 21

√x² = √21

x = 4.58

13. a² + b² = c²

(1/5)² + (3/5)² = c²

1/25 + 9/25 = c²

10/25 = c²

√10/25 = √c²

√10/√25 = √c²

√10/5 = c

14. a² + b² = c²

a² + (4/9)² = (8/9)²

a² + 16/81 = 64/81

a² + 16/81 - 16/81 = 64/81 -16/81

a² = 48/81

√a² = √48/81

a = √48/√81

a = 4√3/9
