Question

Find the missing length for the right triangle described below. B = 21 ft, c=27 ft. Find side a. Round to the nearest whole number

Answer 1

16.97 ft

Explanation:

According to the scenario, computation of the given data are as follows,

Side B = 21 ft

Side c = 27 ft

As we know, formula for right triangle is as follows,

`a^(2) + b^(2) = c^(2)`

`a^(2) = c^(2) - b^(2)`

So, by putting the value in the formula, we get,

`a^(2) = 27^(2) - 21^(2)`

`a^(2)` = 729 - 441

`a^(2)` = 288

a = 16.97 ft

Hence, the length of the side for the right triangle is 16.97ft.
