ACT Challenge Question 15: Hey Girl, What’s Your Sine?

Magoosh ACT Challenge Question

 

Who wants to do some trigonometry during the summer? You do! Remember back when you were 12 and your older brother was doing trig homework and you thought, “I can’t wait until I am that cool?” Well, now you are that cool. Cool enough to take on our ACT Math Challenge Question of the week. The question below comes straight from our Magoosh ACT test prep product (which all the cool kids are doing by the way). Think you can solve it? Post your explanation and how you got it in the comments, and we will share the solution on Friday!

If sine theta = – 3/5, which of the following could be true about theta?
