Answer:
Step-by-step explanation:
1. You divide 5 by both sides, which will give you
2. You then square both sides of the equation, which will give you
3. Since the equation is now one-step, you then do GEMDAS and you will get x=22

Imagine the unit circle. The cot(theta) is a line from (0,1) to (-4,1). Imagine it is part of a triangle with the origin (draw it!).
Then the hypotenuse length is √(1+4²) = √17.
The sine rule says that sin(90)/√17 must equal sin(theta)/4, and sin(90)=1, so
