Question

If a= 2ft and c= 11ft. Find the missing side of the right triangle

Answer 1

Answer:

$\sqrt{117}$ or $3\sqrt{13}$

Step-by-step explanation:

The formula for finding the any side of the triangle is

$a^{2}+b^{2} =c^{2}$

We know that a=2 and c=11, so we can go ahead and plug those into the formula.

$2^{2}+b^{2} =11^{2}$

$4+b^{2} =121$

To find side b, we have to make it alone on one side. Subtract 4 on both side.

$b^{2} =117$

Now square root both sides, and that leaves us with:

$b=\sqrt{117}$ or $3\sqrt{13}$
