It would have to be 3 because distance can't be a negative number.
The answer is 73, simple math
Answer : 110 degree
To find angle 1 , we apply outside angle theorem Lets name each point Measurement of arc EF=280 degrees
Measurement of arc GH = 60
Angle D = angle 1
Please refer to the theorem attached below

Now we plug in the values

angle 1 = 110
Measurement of angle 1 = 110 degrees
