Question

The hypotenuse of a right triangle measures 20 cm and one of its legs measures 7 cm. Find the measure of the other leg. If necessary, round to the nearest tenth

Answer 1

Answer: 18.7 cm

Explanation:

`a^(2) + b^(2) = c^(2) \\c^(2) - a^(2) = b^(2) \\(20)^(2) - 7^(2) = b^(2) \\b^(2) = 351\\b = 18.7`
