Hey friend...

Here is your answer...

By usnig the pythagoras theorem u can easily solve this problem.

(x+9)^2 =(x+7)^2 +x^2

HOPE that it will help you ✌️ ✌️

Answer 2

Answer:

Step-by-step explanation:

It is a rectangle soangle is 90°

By Pythagorean theorem =

( x+9)²=x²+(x+7)²

Identity used=(a+b)²=a²+b²+2ab

x²+9²+2(x)(9)=x²+7²+2(x)(7)+x²

x²+81+18x=2x²+49+14x

2x²-x²+14x-18x+49-81=0

x²-4x-32=0

x²-8x+4x-32

x(x-8)+4(x-8)

(x+4)(x-8)

x=-4. x=8

Side can never be negative so,

x=8
