Answer: B) 60

================================================

Step-by-step explanation:

Whenever the angle theta is between 0 and 90, the reference angle is exactly that value.

It's only when you get to other quadrants is when things get a bit tricky. Right now we're in quadrant 1, often written as Q1.

-------------------

Extra info:

  • If theta is between 90 and 180, then the reference angle is 180-theta. This region is Q2
  • If theta is in quadrant 3, between 180 and 270, then the reference angle is theta-180. The order of subtraction is important since x-y is the not the same as y-x.
  • Lastly, if theta is between 270 and 360 (in Q4), then the reference angle is 360-theta.
  • As you can see, we have four quadrants starting with Q1 in the upper right corner. Then we move counterclockwise to get Q2,Q3 and Q4.
