Answer:
The length of arc S = 47.1
Step-by-step explanation:
The radius of the circle = 10
The central angle of the arc = 3
By formula, S = rΘ
where S is the lenth of the arc
r is the radius of the circle
Θ is the central angle of the arc
substituting the values in the formula, we get
S = rΘ = 10 (3) = 15 = 47.1
The first thing you do is add 90 and 40, which gives you 130... after that you just divide that sum by 2 giving you an average of 65
The arrangement of the Eastern and Western lighthouses and the position of the boat are as shown in the attached diagram.
Using sine rule,
28/Sin 37 = 40/Sin B => Sin B = (40 Sin 37)/28 = 0.8597 => B = Sin ^-1(0.8597) = 59.287°
Therefore,
Angle E = 180 - (37+59.287) = 83.713°
Using the sine rule again;
BW/Sin E = 28/Sin 37 => BW = (28 Sin 83.713)/Sin 37 = 46.246 ≈ 46.27 miles.
The boat is 46.27 miles from the western lighthouse. The correct answer is A.
Answer:
To divide larger numbers, use long division. Unlike the other Big Four operations, long division moves from left to right. For each digit in the dividend (the number you’re dividing), you complete a cycle of division, multiplication, and subtraction. In some problems, the number at the very bottom of the problem isn’t a 0.
