a right triangle has a hypotensue of length 10 ft and one leg o length 7 ft. how long is the other leg? round the answer to the nearest tenth of a foot.
Accepted Solution
A:
Answer:7.1Step-by-step explanation:By using Pythagorean theorem, a^2+b^2=c^2, we can find the missing length of the leg. a^2+7^2=10^2. 7 is the leg length given and 10 is the hypotenuse. Then we solve from there. a^2+49=100a^2=51(sqrt)a^2=(sqrt)51a=7.14142.....rounded to the nearest tenth is 7.1
