One of the legs of a right triangle measures 3 cm and the other leg measures 18 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.

Answer 1

Using the Pythagorean theorem, we have:

h^2 = 3^2 + 18^2
h^2 = 9 + 324
h^2 = 333
h = √333

We can round this to the nearest tenth by using a calculator or estimating:

h ≈ 18.2 cm

Therefore, the measure of the hypotenuse is approximately 18.2 cm.
