Question

QUESTION 5 (4) APQT is a right-angled triangle with angle T = 90°. Find with reasons PT if PQ = 50cm and TQ = 40cm. T P ود *** -​

Answer 1

PT = 30cm

Explanation:

according to pythagoras theorem:

let PT = x

PQ² = QT² + PT²

50² = 40² + x²

2500 = 1600 + x²

x² = 2500 - 1600 = 900

x = √900 = 30

thus, PT = 30cm
