REMEMBER TO USE PATHAGOREAN'S FORMULA FOR SOLVING RIGHT TRIANGLES HERE!!!! A^2 + B^2 = C^2 NOW YOU CAN SOLVE THIS PROBLEM USING SIMPLE ALGEBRA. 15^2 + 10^2 = C^2 ----> 225 + 100 = C^2 ----> C^2 = 325 ----> C = (SQUARE ROOT OF 25)(SQUARE ROOT OF 13) ----> C = 5(SQUARE ROOT OF 13) I HOPE THIS HELPS YOU!?
