The fee for grass will be $183.00. The fee for the patio will be $39.43 for the concrete. I found the angles for the pond because all angles must add up to 360 degrees in a quadrilateral.
Angles and Dimensions
The angles for the deck will be 48 degrees, 90 degrees, and to figure out the other angle for the deck we added those two together and subtracted it from 180 degrees since all the angles in a triangle add up to 180 degrees. The angle for the patio is 360 degrees since its a circle. A pair of complementary angles in the deck are 48 degrees and 42 degrees which add up to 90 degrees.
