Question

For problems 8 and 9, find the length of the missing side of each right triangle. Round your

answers to the nearest tenth, if necessary. (2 points each)

Answer 1

8. c ≈ 7,2 cm

9. b ≈ 6,7 in

Explanation:

Use the Pythagorean theorem for each of these problems:

8.

`{c}^(2) = {6}^(2) + {4}^(2) = 36 + 16 = 52`

`c > 0`

`c = √(52) ≈7.2`

.

9.

`{b}^(2) = {7}^(2) - {2}^(2) = 49 - 4 = 45`

`b > 0`

`b = √(45) ≈6.7`
