Cosine of an angle is the adjacent leg divided by the hypotenuse.
So cos(60) = a / 12
I'm going to assume it's your last option because it's not in the picture.
<h3>
Answer: C. N </h3>
N stands for Newtons
In terms of SI units, 1 newton = 1 kg m/s^2
It's based off the equation F = ma, which is Newton's second law.

Extra info:
- Choice A is velocity
- Choice B is acceleration
- Choice D is some unit I don't really recognize, so I'm not sure if its nonsense or it may have some use. Though I'm sure that N/s isn't a measurement of force.
Answer:
21 cm
Step-by-step explanation:
The two pieces have a length ratio of 1 : 4, so the shorter piece is 1/(1+4) = 1/5 of the total length.
105 cm/5 = 21 cm
The shorter piece is 21 cm.
_____
We assume you can figure out how to write only the digits of the number.
Answer:

Step-by-step explanation:
To solve the problem, you must expand the trigonometric expression using the information given.

Answer:
22,500 =2p
Step-by-step explanation:
Because the price of the new car is the price of the old car times 2.
22,500 =2p
First you get P alone. P is being multiplied by 2 so you divide it by 2 so it cancels out.
11250 = p
When you do something to one side of the equation you do the same to the other side so they are still equal to each other.
