If ∠C=90°, c = 17, and a = 15, then b = 8.
For all right triangles= a squared plus b squared = c squared
15^2 + 8^2 should = 17^2 for this to be correct.
225+ 64= 289
There fore its true.
Just remember the formula and you should be able to find any side of a right triangle if you have the other two sides. Good luck!
