myrzilka [38]

Answer:

Step-by-step explanation:

Comment

You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle

Equation

Cos(x) = a/c the way you have labeled it.

Givens

a = 9

c = 18

Solution

Cos(x) = a / c

Cos(x) = 9 / 18

cos(x) = 1/2

x = cos-1(1/2)

x = 60 degrees

Answer

x = 60

The perimeter of a rectangular pool is 314 m.
ycow [4]

Answer:

The length is 91 meters

Step-by-step explanation:

The perimeter formula is 2W · 2L = 314

We know the width is 66 m, so we can then say:

132 · 2L = 314

-132          -132

2L = 182

L = 91

Hope this helped!
