Use trigonometry here.

sinx = opposite side/ Hypotenuse

so, sinx = 4/5 = 0.8

x= sin^-1(0.8) which is 53.13

Hope it helps

Answer:

I am gonna take a guest and say 178 for number 3. And for number 4, the answer is 44.

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area f

otez555 [7]

Answer:

The sprinkler can spread water 18 feet away.

Step-by-step explanation:

We are given the following in the question:

Area formed by watering pattern = 1,017.36 square feet

We have to find the how far the sprinkler spread the water.

The sprinkler covers a circular area. We need to find the radius of this circular area to find the how far the sprinkler spread the water.

Area of circle = $A = \pi r^2$

Putting values, we get:

$1017.36 = 3.14 r^2\\\\r^2 = \dfrac{1017.36}{3.14}\\\\r^2 = 324\\r = \sqrt{324} = 18\text{ feet}$

Therefore, the sprinkler can spread water 18 feet away.
