Sagot :
30 inches is the length of the hypotenuse of the triangles.
in order to answer this problem you'll need to use pythagorean theorem
c square = the square root of a^2 + b^2
9^2 + 12^2 = 225
then the square root of 225 is 15
the hypotenuse is 15
c square = the square root of a^2 + b^2
9^2 + 12^2 = 225
then the square root of 225 is 15
the hypotenuse is 15
