First, you have to know what is the law of Sine?
(Refer to this website for more information: https://www.mathsisfun.com/algebra/trig-sine-law.html )
<span>a/sin A</span><span> = </span><span>b/sin B</span><span> = </span><span>c/sin C
in this case: 13/sin59=14/sinB, => sinB=(sin59)*14)/13 use your calculator:
B is about 67 degree.
the three angles make a total of 180 degree, so C=180-59-67=54
again, use law of sin, to find out c
13/sin59=c/sin54 =>c is about 12
I don't see how to form the other triangle.</span>
Answer:
y= -.5x+2
Step-by-step explanation:
You can't solve it without another piece of information, so the most you can do is write an equation (3b+ 4p), and once you know how many boxes he bought and the total (to figutre out how many pounds) or how many pounds and the total (to figure out how many boxes) or just the number of boxes and the number of pounds you can figure the problem out.
Answer:
28%
Step-by-step explanation:
Here is the missing table from the question:
Speed (mph) Number of Vehicles
36-40 2
41-45 14
46-50 18
51-55 12
56-60 4
Given: A police officer records the speeds of vehicles on a road.
Now, finding the percent of vehicles traveling between 41 and 45 miles per hour.
First, calculating the total number of vehicles.
Total vehicles= 
Vehicles travelling at speed of 41-45 mph= 14
Formula; percent of vehicles traveling between 41 and 45 mph= 
⇒ Percent of vehicles traveling between 41-45 mph= 
∴ Percent of vehicles traveling between 41-45 mph is 28%
3pie+12mm is the correct answer (A)
