Answer:
a = 61 degrees
b = 119 degrees
Explanation:
These are vertical angle....so whatever is across from that angle, will have the same angle measurement....
What number is across from A? 61 degrees, which means that therefore A will be 61 degrees as well, since it's a vertical angle
What number is across from B? 119 degrees, which means that therefore B will be 119 degrees as well, since its a vertical angle
Now a whole cirlce is 360 degrees, if we add up all these angles we should get 360
119 + 119 + 61 + 61 = 360
238 + 61 + 61
238 + 122
360
Correct!
Hope this helped you!
