Question

what will be the PR=
​

Answer 1

To Find:

The length of side PR.

Explanation:

The sides on the equal angles of an isosceles triangle are equal in measure.

Solution:

By Pythagoras Theorem, we get

PR = √PQ^2 + QR^2

PR = √25 + 25

PR = √50

PR = 5√2

Answer:

The length of the side PR is 5√2 .

Answer 2

$\sf\large\underline\red{Answer:-}$

PR = 5√2

$\sf\large\underline\red{Explanation:-}$

ωє кησω тнαт,

$\sin\alpha = \frac{side \: opposite \: to \: \alpha }{hypotenuse}$

тнєяєƒσяє,

ѕiη R = PQ/PR

✍ sin 45° = 5/PR

✍ 1/√2 = 5/PR

✍ PR = 5√2
