Answer:
20°
Step-by-step explanation:
1) Opposite angles are equal, so the opposite will be 140°.
2) Then, you do 140+110+90+90 (since A and D are at right angles) which gets you 430°
3) Finally, since its a pentagon, you do 540° - 430° which is 110°
Because you are subtracting a higher number from the original number the answer will be negative:
5-6 = -1
