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.
Answer:
-6 is going to the left while positive 2 is going the opposite way
Answer:
46
Step-by-step explanation:
46
Remember the equation for the volume of a sphere:
Since we know the volume, we can set the formula equal to this value and find our radius, and thus our diameter.
- Divide both sides of eqution by
- Multiply right side terms together
- Take the cube root of both sides
- Given that
, we find 
Our answer is 4 in.
