Question

In triangle pqr and triangle lmn angle Q is equal to angle and is equal to 90 degree PR is equals to Ireland and PQ is equals to a lamp if angle P is equal to 3
(please be quick )​

Answer 1

$\huge\bf\mathfrak\green{An}\red{sw}\blue{er}$

$\bf \underline{ Given} \: \div$

PQ =15 cm, QR = 8 cm.

${\bf \underline{ \: To \: Find }} : \: PR$

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
