<h3><u>Answer:</u></h3>

The answer is y = 67°.

<h3><u>Step-by-step explanation:</u></h3>

56 + y + (180 - 123) = 180
=> 56 + y + 57 = 180
=> y = 180 - 113
=> y = 67°

<h3><u>Conclusion:</u></h3>

Therefore, the answer is y = 67°.

Abigail made a quilt that has the area of 4,800 sq. inches. The length of the quilt is 1 1/3 times the width of the quilt. What

Aliun [14]

For this case we model the problem as a rectangle.
The area of the rectangle is given by:
A = (w) * (l)
Where,
w: width
l: long
Substituting values we have:
4800 = (w) * ((1 1/3) * w)
We rewrite:
w ^ 2 = 4800 / (1 1/3)
w ^ 2 = 3600
w = root (3600)
w = 60 in
The long will be then:
l = (1 1/3) * w
l = (1 1/3) * (60)
l = 80 in
Answer:
the dimensions of the quilt are:
w = 60 in
l = 80 in
