Answer: -40
Multiply 2 by 4.
8+4•3-30•2
Multiply 4 by 3
8+12-30•2
Multiply-30 by 2
8+12-60
Simplify by adding and subtracting:
Add 8 and 12
20-60
Subtract 60 from 20
-40
7y = 84
y = 84 /7
= 12
So, y =12
A full rotation is 360 degrees so the required angle is 360/12 = 30 degrees.
I believe the correct answer would be 5,1,3 :)
