Shorter leg of a right triangle is 7ft shorter than the longer leg.
The hypotenuse is 7ft longer than the longer leg.
Find the side lengths of the triangle.
I cant seem to get my head around this.
(x-7^2)+(x+7^2)=?? Sorry, pretty fresh to this.
Let the length of the longer leg, be L
Then the length of the shorter leg is: L - 7, and length of hypotenuse is: L + 7
Using Pythagorean theorem:
, we get: 
Can you now solve this for L, the longer leg, and subsequently, the shorter leg and the hypotenuse?
If not, say so, and you might get further help!
