The monthly cost (in dollars) of water use is a linear function of the amount of water used (in hundreds of cubic feet, hcf). the cost for using 17 hcf of water is $32.99, and the cost for using 40 hcf is $66.34. what is the cost for using 37 hcf of water?

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

∠cbe and ∠deb are same-side interior angles.

i took the test

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
