One of the legs of a right triangle measures 5 cm and its hypotenuse measures 9 cm.

Find the measure of the other leg. If necessary, round to the nearest tenth.

Can someone help please and thanks

Answer 1

answer is 7.5

`{9}^(2) = {5}^(2) + {x}^(2) \\ 81 = 25 + {x}^(2) \\ - 25 \: \:- 25 \\ 56 = {x}^(2) \\ √(56) = √(x) \\ 7 .4833... \\ 7.5`
