Answer 1

Answer: C) 180 or 0

====================================

Work Shown:

Let y = sin(x). Solve for y then solve for x

-4+6*sin(x) = -4+4*sin(x)

-4+6*y = -4+4*y ... replace sin(x) with y

6y-4y = -4+4

2y = 0

y = 0/2

y = 0

sin(x) = 0 ... plug in y = sin(x)

x = arcsin(0)  or  x = 180-arcsin(0)

x = 0 or x = 180

We have two solutions here since

sin(0) = 0 and sin(180) = 0

The solutions x = 0 and x = 180 fit in the interval $0 \le x \le 180$
