Find the area.
3 ft.
9 ft.
4 ft.
5 ft.

35ft

Step-by-step explanation:

It's easiest to split the shape into two sections.

The bottom rectangle is 4ft x 5ft = 20ft

The upper rectangle is 3ft x 5ft = 15ft. The reason why it is not 3ft by 9ft is because I subtracted 4 from 9 because I did not use the full side length.

Then 20ft + 15ft = 35ft

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°
