The angle of depression of a boat at sea from a 100 foot lighthouse is 20 degrees. Find the distance to the boat.not sure how to solve this..

Answers

Answer:

As per the statement:

The angle of depression of a boat at sea from a 100 foot lighthouse is 20 degrees.

We draw the figure for this problem as shown below:

Height of the lighthouse(BC) = 100 foot

Angle of depression = 20 degrees.

Since, angle of depression is equal to the angles of elevation

i.e, $\angle DCA = \angle CAB = 20^(\circ)$

using tangent ratio:

$\tan \theta = \frac{\text{opposite side}}{\text{adjacent side}}$

Here,

Opposite side = BC = 100 foot

Adjacent side = AB

Angle of elevation: $\theta = 20^(\circ)$

Substitute these to solve for AB:

$\tan 20^(\circ) = \frac{100}{\text{AB}}$

$\text{AB} =(100)/(\tan 20^(\circ))$

$\text{AB} =(100)/(0.36397023426)$

Simplify:

AB = 294.375362123 foot

Therefore, the distance to the boat approximately is 294.4 foot

Final answer:

By using the tangent function with the given height of the lighthouse and the angle of depression, we can solve for the distance to the boat, which is approximately 274.1 feet.

Explanation:

In this scenario, we can use trigonometry to find the distance to the boat. Since we know that the lighthouse is 100 feet high and the angle of depression is 20 degrees, this fits the scenario for a tangent function, where tangent of an angle equals the opposite side divided by the adjacent side.

Setting up our function, we get tan(20) = 100/ distance to the boat. Since we want to find the distance to the boat, we can rearrange the equation to be distance to the boat = 100 / tan(20).

Doing this calculation, we find that the distance to the boat is approximately 274.1 feet.

A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 12 cm long and 4 cm wide. The diameter of each semicircle is the width of the rectangle. What is the area of bookmark ? Use 3.14 for pie

Answers

So you know that the are of a rectangle is Length x width, so that part is simply 12x4, which =48 sq cm.
To find the area of the two ends of the bookmark, two semicircles make one circle, so you can just find the area of one circle. The formula for the area of a circle is (3.14) x r². Because the diameter of the circle is the same as the width of the rectangle, half of the 4cm is the radius (2cm).
Area of Circle= (3.14)x(2²)=12.56 cm sq.
Total area = Area of rectangle + Area of Circle
TA= 48 + 12.56
TA= 60.56 sq cm

On Mary's walk she covered the 3-mile distance to the park in one hour. However, the return trip took her one and a half hours. What was her average speed for the round trip?

Answers

the total distance covered by Mary is 6miles
total time spent is 2 and half hours
average speed is given by,total distance divided by total time
so,6/2.5=2.4miles per hour

Final answer:

Mary's average speed for the round trip was 2.4 miles per hour, calculated by dividing the total distance of the trip (6 miles) by the total time for the trip (2.5 hours).

Explanation:

The question deals with calculating average speed for a round trip. The total distance for Mary's walk was 6 miles (3 miles to the park and 3 miles back). The total time taken for the walk was 2.5 hours (1 hour to get to the park and 1.5 hours to return).

Average speed is calculated by dividing total distance by total time. So, the average speed of Mary's round trip is 6 miles divided by 2.5 hours, which equates to 2.4 miles per hour.

How do you subtract an integer from another integer without using a number line or counters

Answers

Okay, so, I think I understand your problem. Not everyone knows how to subtract the different positive and negative integers, and not everyone is great at math. I understand that, so that is why I will give you a couple of tips. First off, whenever you are subtracting a negative integer and another negative integer, the answer will always be negative. When you are subtracting two positives, depending on the number values, they will either be positive or negative. And when subtracting a positive and negative, the answers will always be positive. Other then that, you can use mental math, or write out the problems on a sheet of paper.
