The Martins' swimming pool is a square and is in the center of a square plot that is 35 meters on a side. They have 1,104 square meters of lawn. How long is a side of the pool?

side of the pool = 11 m

Step-by-step explanation:

Square Plot:

side = 35 m

Area = 35 * 35 = 1225 sq.m

Area of  lawn = 1104 sq.m

Swimming pool:

Area of the Swimming pool = 1225 - 1104 = 121 sq.m

side * side = 121 = 11 * 11

side = √11 * 11

side of the pool = 11 m

step-by-step explanation:

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
