The answer to this question is -21
Here's something I learned, if that's a go math text book the answers are always in the last couple pages of the book
Don't be worried friend :)
-(y + 2) + 8 = 3
=> -(y + 2) = -5
=> y + 2 = 5
=> y = 3
A divide by sin A = b divide by sin B
1. 27 divide by sin 68=22 divide by sin x
Sin x=sin 68 times 22 divide by 27
Sinx=0.65696
X=71.7 degrees
8x - 3x - 7 = 23
5x - 7 = 23
5x = 30
x = 30/5 = 6
