4. Ashley has a sprinkler that has several varieties of coverage. The 30 deg setting on the sprinkler
head sprays water a distance of up to 20 feet from
the head.
b) If she was to measure the rounded edge sprayed
by the sprinkler spray what would the length be to
the nearest tenth of a foot

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

14 x 10 5

step-by-step explanation:

10 5 = 100,000

14x10,000 = 140,000

if the rectangular pool has a area of 192 square ft. and length of 15 ft. you must divide 15 into 192. 192 ÷ 15 = about 13 ft.
