Question 1064903
.
One leg of a right triangle is 4 less than the other leg. The square of the hypotenuse of the right triangle is 80. 
How long are the legs of the right triangle. I tried very very hard for 1 hour but got nowhere
~~~~~~~~~~~~~~~~~~~~~~~~~


{{{x^2 + (x+4)^2}}} = 80.


x = 4.


The legs are 4 and 8 units.
