Answer:
Step-by-step explanation:
Angle C and angle with 120 degrees measure are alternate and their measurement is equal so C = 120
angle C and angle B are supplementary and so their sum is equal to 180
B = 180 - 120
B = 60
angle D and angle B are also alternate so their measure is also equal to each other therefore
D = 60
Answer:

Step-by-step explanation:
Since
due to
is an angle bisector, we have the following:

Answer: 176 mins
Since 2 hours is 120 mins and 1 hour is 60 min. You have to add 56 and 120 which is 176 mins easy done.
