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.
