Recall:
The
tan of the measure of an angle is the ratio of the opposite side to the adjacent side to that angle, that is :
![\displaystyle{ \tan x^{\circ}= \frac{opposite\ side}{adjacent \ side}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%5Ctan%20x%5E%7B%5Ccirc%7D%3D%20%5Cfrac%7Bopposite%5C%20side%7D%7Badjacent%20%5C%20side%7D%20)
.
Since this ratio is 3/y, we denote the opposite side, and adjacent side respectively by 3 and y.
(Technically we should write 3t and yt, but we try our luck as we see y in the second ratio too!)
Similarly,
![\displaystyle{\cos x^{\circ}= \frac{adjacent\ side}{hypothenuse}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%5Ccos%20x%5E%7B%5Ccirc%7D%3D%20%5Cfrac%7Badjacent%5C%20side%7D%7Bhypothenuse%7D%20)
.
The adjacent side is already denoted by y, so we denote the length of the hypotenuse by z.
Now the sides of the right triangle are complete.
![\displaystyle{ \sin x^{\circ}= \frac{opposite\ side}{hypotenuse}= \frac{3}{z}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%5Csin%20x%5E%7B%5Ccirc%7D%3D%20%5Cfrac%7Bopposite%5C%20side%7D%7Bhypotenuse%7D%3D%20%5Cfrac%7B3%7D%7Bz%7D%20%20)
Answer: A
Answer:
The answer is 27, 53, and 62
Step-by-step explanation:
This is the answer because 27 is the lowest and then 53 and then you have 62 because it is the biggest.
Answer:
H (the second graph)
Step-by-step explanation:
Answer:
5 years
Step-by-step explanation:
use the I = Prt simple interest formula
Answer: The correct answer is Choice D.
Step-by-step explanation: The correct answer is choice D.
Y = the total amount money that Kelly earned
X = the cost of each manicure
So, in choice D, the total amount that Kelly earned equals 12 times the cost of the manicure plus the 60 in tips that she received for the day.
