Question

le A right triangle has a hypotenuse of 10m and a leg of 5m. What is the length of the second leg? Round to the nearest tenth.​

Answer 1

Length of 2nd leg is 8.7m.

Explanation:

a^2 + b^2 = c^2

Substitute.

5^2 + b^2 = 10^2

Solve.

25 + b^2 = 100

100 - 25 = 75

sqrt(75) = 8.66

Round.

8.66 ---> 8.7.
