Answer:
c. 30
Step-by-step explanation:
Reference angle =
= ?
Hypotenuse = 23
Adjacent side = 20
Thus, applying CAH:
![Cos(/theta) = \frac{adj}{hyp}](https://tex.z-dn.net/?f=%20Cos%28%2Ftheta%29%20%3D%20%5Cfrac%7Badj%7D%7Bhyp%7D%20)
![Cos(/theta) = \frac{20}{23}](https://tex.z-dn.net/?f=%20Cos%28%2Ftheta%29%20%3D%20%5Cfrac%7B20%7D%7B23%7D%20)
![/theta = cos^{-1}(\frac{20}{23})](https://tex.z-dn.net/?f=%20%2Ftheta%20%3D%20cos%5E%7B-1%7D%28%5Cfrac%7B20%7D%7B23%7D%29%20)
≈ 30° (nearest degree)
Answer:
There are 52 cards in a deck. Four kings and 13 clubs. So the probability of choosing a king or a club is 17/52. The probability that it's both a king and a club is 1/52 because it's only one king that's a club. Hence for drawing a card from a deck, each outcome has probability 1/52. The probability of an event is the sum of the probabilities of the outcomes in the event, hence the probability of drawing a spade is 13/52 = 1/4, and the probability of drawing a king is 4/52 = 1/13.

Answer:
B.) 25 dollars times 0.20
Step-by-step explanation:
0.20 = 20%.
About 1.6 miles.
You divide the 4 by 30 to get the distance per minute and multiply it by 12.
