Question

Determine the missing length in each right triangle using thePythagorean theorem. Round the answer to a whole number as needed.

Answer 1

Answer: CE = 13

Explanation:

The Pythagorean theorem is expressed as

hypotenuse^2 = one leg^2 + other leg^2

From the diagram,

CE = hypotenuse

CD = 7

DE = 11

Thus,

CE^2 = 7^2 + 11^2 = 49 + 121 = 170

CE = √170

CE = 13
