sorry for bad handwriting but it's natural

Answer 2

Answer:

As the triangle is a right angled triangle.

So by Pythagoras theorem

{ PR}^{2} = { PQ }^{2} + { QR}^{2}

{ PR} ^{2} = {15}^{2} + {8}^{2}

{ PR }^{2} = 225 + 64

{ PR }^{2} = 289

PR = \sqrt{289}

PR = 17

Therefore , length of the hypotenuse = 17cm
