Answer:
16.97 ft
Step-by-step 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,
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]a^{2} = c^{2} - b^{2}[/tex]
So, by putting the value in the formula, we get,
[tex]a^{2} = 27^{2} - 21^{2}[/tex]
[tex]a^{2}[/tex] = 729 - 441
[tex]a^{2}[/tex] = 288
a = 16.97 ft
Hence, the length of the side for the right triangle is 16.97ft.
