Answer:
27.5 degrees
Step-by-step explanation:
Since the shape is a circle that means the degree of the angle is 360 but there are 4 corners so you have to divide 360/4 that's when you get 90. Angle B has a formula for solving it so all you do is reverse the formula. If it says -20 that means you have to add to 90, giving you 110. You then will take (4x) and divide by 110 because you have to do the opposite of what it says and that's when you get 27.5 degrees. Please give me the brainliest answer.
