To find x:
You must know that the sum of angles in triangle =180 so
69+72+x=180
X=39
For y (you need to know 2angles to find it )
So
180-69=111
111+27+y=180
y=42

Answer:

69°+72°=141°

180°-141°=39°

x=39°

180°-69°=111°

111°+27°=138°

180°-111°=69°

y=69°

A Rectangular parking lot has a length that is 4 yards greater than the width the area of the parking lot is 480 square yards. F
Kipish [7]

Answer: length of rectangular parking lot = 24 yards

Width of rectangular parking lot = 20 yards.

Step-by-step explanation:

Let L represent the length of the rectangular parking lot.

Let W represent the width of the rectangular parking lot.

The rectangular parking lot has a length that is 4 yards greater than the width. It means that

W = L - 4

The formula for determining the area of a rectangle is expressed as

Area = LW

The area of the parking lot is 480 square yards.. It means that

LW = 480- - - - - - - - - - 1

Substituting W = L - 4 into equation 1, it becomes

L(L - 4) = 480

L² - 4L = 480

L² - 4L - 480 = 0

L² + 20L - 24L - 480 = 0

L(L + 20) - 24(L + 20) = 0

L - 24 = 0 or L + 20 = 0

L = 24 or L = - 20

Since the length cannot be negative, then L = 24

W = L - 4 = 24 - 4

W = 20
