Question

A right triangle is shown at right. Mark plans to use the Pythagorean Theorem to find the length of the missing side

Answer 1

Step-by-step explanation:

a² + b² = c²

b = 6 in

c = hypotenuse = 10 in

a² + 6² = 10²

a²+ 36 = 100

subtract 36 from both sides:

a² + 36 - 36 = 100 - 36

a² = 64
