Solve for each variable and tell how you found the value of each.
AleksAgata [21]

Answer:

A:38 c:54

Step-by-step explanation:

First off, I did the easiest which was a. i found the value of A by subtracting 180 by 142. because a flat line is 180 degrees.

For C, It was more difficult. I subtracted 88 by the value of A, since the value of A is the same as the one next to 88. So I subtracted 126 (88+38) and got 54.  

Fortunately, I couldn't figure out B though, but i think it is a similar answer to c.

crimeas [40]
The answer is B, 30 x 5 The answer is reasonable. Ryder is correct. It reasonable because if 25 x 5 is 125, then 30 x 5 won't be too much to be unreasonable. 30 x 5 is 150, therefore it is only 25 windows higher, so it is reasonable. Hope this helps! :)
