Angles B and D are supplementary angles, so if B's angle is 30 degrees, then D's angle at y would be 150, since they have to add to 180.
In short, angle y = 150

The surface area of the box is <u>1048 square inches</u>
<h3>How to calculate the total surface area of the box</h3>
The formula for calculating the surface area of the prism is expressed as:
Surface area = 2(lw + wh +lh)
Given the following
l = 20in
w = 8in
h = 13in
Substitute the given parameters'
Surface area = 2(lw + wh +lh)
Surface area = 2(20(8) + 8(13) +20(13))
Surface area = 2(160+104+260)
Surface area = 1048 square inches
Hence surface area of the box is <u>1048 square inches</u>

Answer:
x = -1 or 5
Step-by-step explanation:
From the expression (x +1) (x - 5)
We’re to solve for x.
Therefore,
x + 1 = 0
Subtract one from both sides
x + 1 - 1 = 0 - 1
x = -1
x - 5 = 0
Add five to both sides
x - 5 + 5 = 0 + 5
x = 5
