Answer:
You will need to convert to degrees when you are taking a right-triangle approach to trigonometry. In other words, if you are not utilizing aspects of the unit circle, you should convert to degrees. The opposite would go for radians. When you are taking a unit circle approach, convert degrees to radians.
Step-by-step explanation:
The tax he has to pay is $4.95
The total bill would be $94.95
We know that 24 is 160% more than some recommended number, let's call it "x." This means 1.6 times the recommended number equals 24. Therefore, all we need to do is solve for x.
![1.6x=24](https://tex.z-dn.net/?f=%201.6x%3D24%20%20%20)
![x=\frac{24}{1.6}](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B24%7D%7B1.6%7D%20)
Make sense?
Answer:
29.7 for question 14
15a is 12.1
15b is 14
Step-by-step explanation:
In a 45 45 90 triangle, the legs are congruent, or the same length.
If we call the legs a, then the hypotenuse would be root 2 a.
So if the hypotenuse is 42, we divide by root 2 to get the length of each leg.
That should give us 29.7
In a 30, 60, 90 triangle, the short side is a, then the hypotenuse is 2a, and the longer side is a root 3.
So if the shorter side is 7, the longer side is 12.1, and the hypotenuse is 14.
