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:
$1.36
Step-by-step explanation:
First, add together the prices of all the clothes:
18.28 + 42.39 + 12.97
= 73.64
Then, subtract this from 75:
75 - 73.64
= 1.36
So, he will have $1.36 left after buying the clothes
Side b is adjacent to the 30° angle so use cosine to solve. (soh cah toa)
cos(30°) = b/12
12*cos(30°) = b
cos(30°) is √(3)/2
12*(√(3)/2 ) = b
6√(3) = b
