The height of the ladder on the building is 19.77 feet
<h3>How high does the ladder reach on the building?</h3>
Represent the height of the ladder on the building with h
So, the given parameters are:
Angle, x = 64 degrees
Length of ladder, l = 22 feet
The height of the ladder on the building is calculated using
sin(x) = h/l
Substitute the known values in the above equation
sin(64) = h/22
Multiply both sides by 22
h = 22 * sin(64)
Evaluate the product
h = 19.77
Hence, the height of the ladder on the building is 19.77 feet

Answer:
Step-by-step explanation:
Use the distance formula.
Subtract the x-coordinates and square the difference.
3 - 7 = -4; (-4)^2 = 16
Subtract the y-coordinates and square the difference.
4 - 2 = 2; 2^2 = 4
Add the differences and take the square root of the sum.
16 + 4 = 20; sqrt(20) = sqrt(4 * 5) = 2sqrt(5)
distance = 2sqrt(5)
You can use the distance formula which does the same thing.
The bearing of the plane is approximately 178.037°.
<h3>Procedure - Determination of the bearing of the plane</h3><h3 />
Let suppose that <em>bearing</em> angles are in the following <em>standard</em> position, whose vector formula is:
(1)
Where:
- - Magnitude of the vector, in miles per hour.
- - Direction of the vector, in degrees.
That is, the line of reference is the semiaxis.
The <em>resulting</em> vector (), in miles per hour, is the sum of airspeed of the airplane (), in miles per hour, and the speed of the wind (), in miles per hour, that is:
(2)
If we know that , , and , then the resulting vector is:
Now we determine the bearing of the plane (), in degrees, by the following <em>trigonometric</em> expression:
(3)
The bearing of the plane is approximately 178.037°.
