If you look at either diagonal (line joining opposite angles) it forms 2 triangles that are identical, both in size and shape, but that are in different positions. So by finding the area of one using <u>base x height ÷ 2,</u> and then adding them together, you get the area of the polygon.
However, you will find that that would be the same as just doing <u>base x height</u>, so the area of a parallelogram is just that.
since the distance from the outside edges is 26 1/2 feet, divide that by 2 to get the distance from the center to the edge ( 26 1/2 / 2 = 13 1/4 feet)
the stage is 76 feet so divide that by 2 to find the center 76/2 = 38 feet
now subtract the 13 1/4 from 38
38 - 13 1/4 = 24 3/4 feet from the side of the stage to the edge of the trap door
a little easier way would be to subtract the 26 1/2 from 76 and then divide by 2
76-26 1/2 = 49 1/2 / 2 = 24 3/4
Answer:
The missing number would be 22.
Step-by-step explanation:
The missing number would be, lets say <em>x</em>.
(<em>x</em> - 8) / 7 = 2
First, lets multiply 2 by 7.
2 * 7 = 14
Next, lets add 8 to 14.
8 + 14 = 22
The missing number would be 22.
To check this answer, subtract 8 from 22 which would be 14.
Then divide by 7 which would be 2. This answer is correct.
Therefor, the missing number, or x, would be 22.
Hope this helps!
