80°. angle 4 and and 5 are same side interior angles, so they add up to 180°. 180-100=80.

Step-by-step explanation:
Answer=b=1
The polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).
<h3>What is the
Area of a Trapezoid?</h3>
Area of trapezoid = 1/2(a + b)h, where a and b are length of the parallel sides, and h is the height.
Given:
a = 3x + 5
b = x - 2
h = 2x - 5
Thus:
Area of trapezoid = 1/2(3x + 5 + x - 2)(2x - 5)
Area of trapezoid = 1/2(4x + 3)(2x - 5)
Area of trapezoid = 1/2(8x² - 14x - 15)
Therefore, the polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).

No she can't. We could divide 5 1/2 cups by 3/4 cups but there is an easier way.
Let's change 3/4 to .75 and multiply by 10 since we need 10 servings.
.75 x 10 = 7.5 so she would need 7.5 cups or 7 1/2 cups
Since she only has 5 1/2 cups, she does not have enough.
