The answer for Group A. is 0.080 or 0.08
the answer for Group B. 1.07 or 1.070
If you use trigonometry you get x=76 degrees
-3x = 21
Divide -3 from both sides and you get x = -7
1/3x = 6
Divide 1/3 from both sides and you get x = 18
-1/2x = -7
Divide -1/2 from both sides and you get x = 14 (you get a positive answer from 2 negatives)
Dividing 1/3 is just multiplying by 3, and dividing -1/2 is just multiplying by -2
