Question

(Pythagorean theorem) find the missing side length. Round to the nearest hundredth (show steps)

Answer 1

The length of the missing side is 7.5

Explanation:

let the missing side be x

`{9.9}^(2) = {6.5}^(2) + {x}^(2)`

98.01 = 42.25 + x^2

x^2 = 98.01 - 42.25

x^2 = 55.76

`\sqrt{x {}^(2) } = √(55.76)`

x = 7.5 or 7.47
