ganeshie8 · Answer

hypotenuse and one leg are given

ganeshie8 · Answer

you need to find the other leg, right ?

anonymous · Answer

right

ganeshie8 · Answer

its easy, we have a formula for right triangle.

hypotenuse^2 = leg1^2 + leg2^2

ganeshie8 · Answer

9^2 = 4^2 + leg2^2

=>

81 = 16 + leg2^2

ganeshie8 · Answer

you can solve leg2 now ?

anonymous · Answer

64???

ganeshie8 · Answer

wrong... try step by step

ganeshie8 · Answer

81 = 16 + leg2^2

subtract 16 both sides
=> 81-16 = leg2^2
=> 65 = leg2^2
