If <span>point M is the midpoint of segment QR then QM = MR</span>
16 + x = 2(x+2)
16 + x = 2x + 4
16 - 4 = 2x - x
12 = x
If x = 12 then
QR = 2*QM = 2(16+x) = 2*(16+12) = 2 * 28 = 56
its b because if you multiply 3 x 6 you get 18 which is outside the radical

Answer: B) 60</h3>
================================================
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.
