Question

In a triangle PQR right angled at Q,PR+QR=25

Answer 1

hey mate in your question it must be

PQ = 5CM

PR + QR = 25CM

PR = 25 - QR

ACCORDING TO PYTHAGORAS THEOREM

PR² = PQ² + QR²

(25-QR)² = 5² + QR²

25² + QR² - 50QR = 25 + QR²

625 - 50 QR - 25 = 0

50QR = 600

QR = 12CM

PR = 25 - QR

PR = 25 - 12

PR = 13CM

HOPE IT WILL HELP YOU DEAR FRIEND

THANKS
