Thats 29 squared on the hypotenuse and x+3 on the opposite and just x on the adjacent. I cant figure what to do with the 29 after it is given an exponent of 2 and taken out of square form.

yeah, but what do with 3x+6x+9=29?I am not sure how to solve this quadratic expression. I know 3x is raised to the second power, just can't figure how to use the tools on this site yet.

I got it now, with the answer 2. I kept thinking it was 3x instead of 2x. Thanks for the help!

x² + (x + 3)² = (√29)²

x² + x² + 6x + 9 = 29

2x² + 6x – 20 = 0

x² + 3x – 10 = 0

x = [– 3 ± √(3² + 40)]/2

= [– 3 ± √49]/2

= (– 3 ± 7)/2

= taking + ve values

x = (– 3 + 7)/2 = 2

sides are 2, 5, √29 units
