You can put this solution on YOUR website! The area of aright triangle is 84 square ft.; its hypotenuse is 25ft. Find the length of its two sides.
-----------
a*b/2 = 84
a^2 + b^2 = 25^2
-----------
Can you do the rest?
You can put this solution on YOUR website! we have two equations here
x^2 + y^2 = 25^2
(xy)/2 = 84
the two equations become
x^2 + y^2 = 625
xy = 168
solve second equation for y and substitute in first equation
x^2 + (168/x)^2 = 625
x^2 + (28224/x^2) = 625x^2
x^4 + 28224 = 625x^2
x^4 -625^2 + 28224 = 0
solve using quadratic formula and we get two sets of solutions
x^2 = 49, which means x = 7 feet and y = 24 feet
x^2 = 576, which means x = 24 feet and y = 7 feet
