Ok let's start with the right side where there are only two angles. We know that a full circle has a total of 360 degrees. Line CAF splits the circle in the middle so we know that each side has half of 360 and is 180 degrees. On that right side we will do 180-132 to get 48 degrees for angle eac. That takes care of that side.
For the next one we see that angle cag is a right angle (90) so we did like we did for the last problem and subtract the angle we have (51) from what we know the total to be (90). The equation should look like this: 90-51= 39 degrees for angle dac. Do the same process for the last missing angle: 90-65=______.
For angle ead, just add up what you got for angles dac and eac. For the last one do the same and add up what you have for angles dac, dag, and gah.
I hope this helps!!!!
