So hmm notice the picture below
the side of the river, needs no fencing, since the river is there
and thus the perimeter of the pen, is just w + w + l, or 2w+l
thus
take the derivative of P(w), set it to zero, and check for any critical points, then run a first-derivative test for any minimum

Answer:
<u><em>BC=15.01</em></u>
Step-by-step explanation:
Line segment BC can also be represented by '?'. To solve for BC, find the value of '?'
Use the tangent ratio:
Because you need the value opposite the given angle and you are given the length of the side adjacent the given angle (hypotenuse does not count as the adjacent side, EVER (btw)). Let 65° be X and let x replace'?'.Insert the appropriate values:
Solve by isolating x. Multiply 7 to both sides:
Insert this equation into a calculator:
Round to the nearest hundredth:
So, BC is 15.01
<em>Finito.</em>
