Are you familiar with trig ratios for this?

not really

Hero:

|dw:1526678752552:dw|

Hero:

\(\sin(\theta) = \dfrac{a}{c}\) \(\cos(\theta) = \dfrac{b}{c}\) \(\tan(\theta) = \dfrac{a}{b}\)

Hero:

@hardlyhuman that's your clue.

hardlyhuman:

okay thanks

Hero:

Are you going to try calculating? If so, then which trig ratio are you going to use?

hardlyhuman:

sin

Hero:

Great. Let me know what you get for your result.

hardlyhuman:

B

Hero:

Can you show the work you did to arrive at B as your correct result?
