Explanation:
First convert 2 radian to degrees
3.14 --> 180^@
1 radian --> 180/(3.14)
2 radian -->
The equation becomes:
10sin(x - 114.65) = - 7
sin (x - 114.65) = -7/10 = - 0.7
Calculator and unit circle -->
Arc
arc (- 44.43) is co-terminal to arc
and arc
a. x - 114.65 = 224.43 -->
b. x - 114.65 = 315.57 -->
