You would start by finding the area of the circle and then finding the area of the rectangle. After finding both, subtract the area of the rectangle from that of the circle. <span />
Ah...Trigonometry is fun!
The law of sines states:

The transitive property (switching the orders of the equations) applies here. Therfore, we can say that

We then plug in our given values to find C


Solving, we get 0.8557316387.
We're not done yet!We are trying to find an angle measure, so we'll do the inverse of the ratio we used (sin).
arcsin0.8557316387 (arcsin is the same as inverse sin)
=
58.8 (approximate)
So the measure of angle C is 58.8. You could check this by reinserting it into the equation

Answer:
-2 is the slope
Step-by-step explanation:
Answer: c=24
Step-by-step explanation: 15×3=45. 8×3=24. Just multiply both the numerator and denominator by 3.
Answer:
Step-by-step explanation:
plug 3 into x
2(3)^2+(3)
2(9)+3
18+3
21
f(3)=21
