Answer:
BC = 18tan(40°)
Step-by-step explanation:
The leg of the triangle can be explained using tan
Tan(angle) = opposite/adjacent
Plug in and simplify to get the answer
1. Know that: (1) in 28 miles, there are 147,840 ft because 28*5280, (2) radius is 7/6 because that is (2 1/3)/2, (3) C=2(pi)(7/6) or pi*7:3
2. To find revolutions per minute, you take 147,840 and divide it by the circumference to get revolutions per hour, which is about 20168.11439. Then, divide this by 60 to find revolutions per minute: 336.1352398 revolutions/min.
3. Then, to find the angular measure in radians you take the revolutions per minute and multiply it by 2pi.
Here, Slope (m) = y2 - y1 / x2 - x1
m = 2-(-7) / 3 - (-4)
m = 2 + 7 / 3 + 4
m = 9 / 7
Equation would be: y - 2 = 9/7 (x - 3)
& y + 7 = 9/7 (x + 4)
In short, Your Answers would be Option E & C
Hope this helps!
