Answer:-74
Step-by-step explanation: When you are in the megatives, less is more! So -74 is actually greater then -75
21 times because you need 7/4=1 gallon and 3/4 just for one and 7x3 =21 so need 21/4
I believe 30 is the answer :)
Since a full circle has 360degrees and this circle only has two angles, subtract the arc of the known angle to find the arc of the unknown angle.
Angle DGF + angle DEF= 360degrees
Angle DGF + 70degrees= 360 degrees
Angle DGF = 290 degrees
The arc of the unknown angle is 290 degrees
