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

or

Step-by-step explanation:

The formula for finding the any side of the triangle is

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

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

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

sites:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
