Answer:
Mrs. Buggie should have Subtracted 13 instead of adding 13
LKA = 94°
Step-by-step explanation:
Lets work backwards from the equation so far:
40 = x+ 13
x + 13 = 40
We should subtract 13 because we are adding a number and 13 to 40
Imagine this:
You have 5 apples, but you bought some more and now you have 10
equation would be:
5+x = 10
subtract 5 from 10 to get 5
So you bought 5 apples
Back to the Question:
40 - 13 = 27
3(27) + 13 = 81+13 = 94°
Answer = 94°

Answer:
Step-by-step explanation:
The need is to find the area of the elongated plus sign inside the rectangle. The area of the rectangle itself is not needed. That elongated plus sign is where we will run into trouble. The center of that plus sign is included in both the vertical strip and the horizontal strip. So when we go to find the area of the plus sign, we include the center in one or the other, NOT BOTH. I included the area in the vertical strip so I eliminated it in the horizontal strip, creating 2 shorter strips on either side of the center.
The area for the vertical strip, including the center:
A = 3 * 26 (3 is the width and 26 is the length)
A = 78 square meters
Now for the horizontal strip...
The horizontal strip minus the center is
14 - 3 = 11; divide that 11 in half and we get the length of each short horizontal strip on either side of the center to be 5.5 meters long. Therefore, each short strip measures 5.5 (we have 2 of them).
A = 3(5.5) + 3(5.5) and
A = 16.5 + 16.5
A = 33
The sum of the long vertical and the 2 shorter horizontal areas is
78 + 33 = 111
Therefore, the total area of the colored portion is 111 square meters.
