Question 593742: Molly has a solar panel with a width of 26in. To get the proper inclination for her climate, she needs a right triangular support frame that has one leg twice as long as the other. To the nearest thenth of an inch, what dimensions should the frame have?
so right triangle a^2+b^2=c^2
2x^2+x^2=26^2
3x^2=676
(3x^2=676)/3
x^2=225
square root the whole thing
x=15 but when i check my work it doesn't add up so i know i must be doing it wrong

so right triangle a^2+b^2=c^2
2x^2+x^2=26^2 ***************** (2x)^2 + x^2 = 26^2
3x^2=676 ************************ 5x^2 = 676
