An in-ground swimming pool often has steps that are made from poured concrete. In the sketch of the steps below, the steps are identical, each measuring 19 inches from side to side, 11 inches from front to back, and 7 inches tall. Calculate the amount of concrete that is needed to form the steps. 19 in.11 in.7 in. The amount of concrete for the steps is cubic inches.

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°

step-by-step explanation:

85.3-64 = 21.3
