the measurements of the ramp are 4ft by 36inches.

so \[c^2=a^2+b^2\]

I'm just not sure where to go from there.

Answer 7

first off, 4ft = ?? inches?

Answer 8

48 inches

Answer 9

, so? which leg is 48, which is 36?

Answer 10

the base is 48?

Answer 11

Answer 13

\[36^2+48^2=3600\]

Answer 14

that is c^2, not c
