Arectangular swimming pool is 25 feet long anf 12 feet wide. it is surrounded by a fence that is h feet from each side of a pool. write the expression for the length of the fence.

The length of rectangular swimming pool = 25 feet

The width of the swimming pool = 12 feet

The pool is surrounded by a fence which is h feet from each side

So, length of fence becomes = 25+2h

Width of fence becomes = 12+2h

The expression for the length of the fence is 25+2h feet

2h because 'h' increases for both ends of the length of the pool.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

sine
