While fishing, you get bored and start to swing a sinker weight around in a circle below you on a 0.21 m piece
I dunno asked:
of fishing line. The weight makes a complete circle every 0.70 s. What is the angle that the fishing line makes with the vertical? [Hint: See Figure 5-10.]

Not enough info.
You need some information about the size of the circle.
If you were given some information about the size of the circle from which you could figure out the radius of the circle, then you could construct a right triangle. 0.21 m would be the hypotenuse, the radius of the circle would be the horizontal dimension, and the angle that the fishing line would make with the vertical would be:
sin(radius/0.21)
You’d use sin because sin is “opposite over hypotenuse”, which in this case is “horizontal over hypotenuse”.
