NOTES:
Since Q is a right angle then PQ and QR are the legs and PR is the hypotenuse. Use the Pythagorean Theorem to solve.
Part A PR = 15.23
Step-by-step explanation:
PQ² + QR² = PR²
6² + 14² = PR²
36 + 196 = PR²
232 = PR²
15.23 = PR
Part B PR = 7.75
Step-by-step explanation:
PQ² + QR² = PR²
PQ² + 14² = 16²
PQ² + 196 = 256
PQ² = 60
PQ = 7.75
