4. Find the area of the polygon

Select the appropriate response:

A) 1200 sq inches
B) 21 square inches
C) 360 sq inches
D) 180 sq inches

Add the top and bottom dimensions together, divide by 2 then multiply that by the height:

10 + 20 = 30

30/2 = 15

15 x 12 = 180

The area is 180 sq. Inches

D) 180 sq inches

Step-by-step explanation:

It's a trapezoid

Area = ½(sum of // sides) × height

= ½(10 + 20) × 12

= 180 in²

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°
