Answer:
90
Step-by-step explanation:
Angle 2 = 180 - 68 = 112
Angle 3 = 90 - 68 = 22
Angle 2 - Angle 3 = 112 - 22 = 90

Let's simplify ~




Therefore, A is the Correct choice !
Answer:

Step-by-step explanation:
∠E = 1/2 (mCD - mAB)
<u>Where mCD = 110° and mAB = 30°</u>
∠E = 1/2 (110° - 30°)
∠E = 1/2 (80°)
∠E = 40°
