<span><u>Answer </u>
132 〖in〗^2


<u>Explanation </u>
Although the diagram was not given, I was able to get it in the internet.
The area of a trapezium is found by the use of the following formula:
Area =1/2 h(a+b)
Where h is perpendicular distance between the two parallel lines, while a and b is are the lengths of the parallel lines.
In this question;
h=12 in
a=8 in
b=3+8+3=14 in
Area =1/2×12(8+14)
=6×22
132 〖in〗^2

Answer:

Option B. 132 inch²

Step-by-step explanation:

Since we know the formula to calculate the area of trapezoid is = \frac{1}{2}(height)(base)

where height of the given trapezoid ABCD is side BE and two parallel sides are AB and DC.

It's given in the question

Side BE = 12 inches

AB = 8 inches

DC = (DF + FE + EC) = (3 + 8 + 3) = 14 inches

Now we put these values in the formula

Area of trapezoid ABCD = \frac{1}{2}(AB+CD).(BE) = \frac{1}{2}(8 + 14).(12)=\frac{1}{2}(22)(12)=(11).(12)=132

Therefore answer is Option B. 132 inch²

How to write the function whose graph of the graph but it shifted to the left 4 units
N76 [4]

Answer:

I would say that it's y = -4

Step-by-step explanation:

Because if you're shifting to the left you are decreasing.

If you were to move left on a graph you'd be going towards the negative side.

Mr. Miller has a 20-foot ladder, which he
dimulka [17.4K]

Answer:

8 ft

Step-by-step explanation:

the ladder will make a right angle triangle with the house. The hypotenuse of the triangle is the ladder, 20 ft, and the height of the triagnle is 18 ft.

Solve for the base of the right angle triangle using pythagorean's theorem:

c=20, a=18, b=?

b^{2}=c^{2} - a^{2}\\b^{2}=20^{2} - 18^{2}

b=\sqrt{72}

b= 8.49 ft

round to the nearest foot,

b = 8 ft

Determine side x. Round to the nearest unit. 20 9 12 5
tatyana61 [14]

Answer:

12

Step-by-step explanation:

First, you will have to use trigonometry. Since the side of the triangleis the opposite of the angle 53 and the hypotenuse, you will use sin.

Sin 53 degrees = opposite side / hypotenuse side.

The opposite side is x and the hypotenuse side equals 15.

sin53= x/15

15 ( sin 53 ) =x

x= 11.97953

Round

x=12
