No incorrect. Use a^2 + b^2 = c^2. C is the length of the hypotenuse. So solve for a or b. Plug in 9 as a or b and 12 as c then solve for the unknown
the answer is B. 12 cm
:) hope i help!
:) hope i help!
Thankz
Two things to keep in mind:
1. a 3 4 5 triangle is a right triangle. This is one
3*3 , 4*3, 5*3
2. The hypotenuse is ALWAYS the longest side of a right triangle.
