Answer: 88°
Step-by-step explanation:
ABCD equals 360°
ABC equals 184
360 - 184 = 176
176/2 = 88
ANOTHER WAY TO CHECK
Rotate the figure straight up, and examine it closely to see that it's a little less than 90°
You see, it is not 90° or 92°, and the change is too small to be 84°. So we determine it's 88 by looking at it NOTE, THIS WILL NOT ALWAYS WORK BECAUSE THE EQUATION IS DIFFERENT THAN THE PICTURE IT'S SUPPOSED TO MATCH.
