From the top of a lighthouse 180 feet high, the angle of depression of a boat is 23o. Find the distance from the boat to the foot of the lighthouse to the nearest foot. (The lighthouse was built at sea level.)

Answers

Answer:

The lighthouse is 424 feet away.

Step-by-step explanation:

There is no other way to do this but to use one of the 6 trigonometry functions.

Drawing

Draw a dotted horizontal line.

judge an angle that could be 23o. Let it slant downward from the left side of the dotted line.

Draw another horizontal line that represents sea level.

Join the left side of the dotted line to the last line you drew. The angle on your right is also 23o.

Function

You have 6 trig functions to choose from. You have the lighthouse height (180 feet) the angle on your right, and the length on the horizontal representing the distance from the lighthouse base to the boat.

You have an angle

You have an opposite side

You have a horizontal line (the adjacent side)

You want to use the tangent function.

Tan(23) = opposite / ad

Tan(23) = 180 / adjacent     Multiply both sides by the adjacent

adjacent*Tan(23)= 180        Divide by Tan(23)

adjacent = 180/Tan(23)

adjacent = 180 / 0.42447

adjacent = 424 feet.

Find two square roots of 121/49

Answers

The square root of the given fraction 121 / 49 will be 11 / 7.

What is a square root?

A number y such that y² = x, or a number y whose square is x, is referred to as the square root of a number x in mathematics.

Given that in mathematics, a number r is said to be the nth root of a number x if it is raised to the power n.

The square root of the given number will be calculated as below:-

Square root = √( 121/49 )

Square root = 11 / 7

Therefore, the square root of the given fraction 121 / 49 will be 11 / 7.

The slope is four thirds (4/3)

Is1/10 and 3/33 epuivalant

Answers

3/33 can be reduced to 1/11 by dividing by 3 on the top and bottom.
1/11 is not equal to 1/10. Although they have the same numerator or number on top, 1, they don't have the same number in the bottom. 
So they are not equivalent.
Hope this helps. 
No,

3/33 equals 1/11 and 1/11 is smaller than 1/10. so they are not equal.

16. The temperature on the ground during a plane's takeoff was -7°F. At 38,000 feet in the air, the temperatureoutside the plane was -29°F. Find the difference between these two temperatures.a. 36 FC. -22°Fb. 36°Fd. 22 F

Answers

The difference between given two temperatures will be  -22^0 F .

What is temperature ?

Temperature is the measure of hotness or coldness of something which is expressed in terms of several scales, including Fahrenheit and Celsius.

We have,

Temperature on the ground =-7^0F

Temperature in the air =-29^0F

So, the difference between temperatures =Temperature in the air  - Temperature on the ground

The difference between temperatures = -29-(-7)            

                                                                 =-29+7

                                                                  =-22^0F

Hence, we can say that the difference between given two temperatures will be  -22^0 F .

The answer is -22°F because you are subtracing -7°F from -29°F.
