Question

please answer my question

Answer 1

PR=QS ie, 5x+2=8x-7=> 7+2=8x-5x => 9=3x => x=3 now PR=5x+2=5×3+2=15+2=17

Answer 2

$HERE IS YOUR ANSWER$

We know that in isosceles trapezium diagonals are equal:

So, PQ = PR

Therefore, 5x+2 = 8x-7

Therefore, 8x-5x = 7+2

So, 3x = 9

So, x = 3

Now, PR = 5x+2 = 5*3+2 = 17
