Question

PQR is a triangle right angled at P. If PQ=13cm and PR=5cm,findQR

Answer 1

Answer:

Step-by-step explanation:

Given PQ = 13cm, PR = 5cm

Angle PQ and PR form a right angle

So the side opposite to the right angle is the hypotenuse or QR

Therefore  PQ² + PR²  =  QR²

[Pythagoras Theorem A² + B² = C²]

Where C is the hypotenuse or longest side of a triangle

So we have

=>  13² + 5² = QR²

=>  169 + 25 = QR²

=>  194 = QR²

=> QR = √194
