To start, let's add on the first side to get 3x + 6x - 6 = 9x - 6. For the second side, we need to distribute the 4 to get 4(2x) + 4(-2), or 8x + (-8) or 8x - 8. Setting these equal, we subtract 8x from both sides to get x - 6 = -8, and adding 6 to both sides gives x = -2.

Let sin(47o)=0.7314 . Enter an angle measure (β ), in degrees, for cos(β)=0.7314

amid [387]

Sinx = cosb => x + b = 90 <=> b = 90 - 47 = 43o
