Find the angle of elevation of the flagpole's top, 31.9m high, from a point 55 m away on ground level.
looks like tanØ = 31.9/55 = .....
use your calculator's 2ndF tan to find the angle
Ah, the age-old question of heights and angles. Well, assuming the flagpole is not leaning to the side and is a perfect upstanding citizen, I can calculate the angle of elevation for you.
Now, let's use our trusty trigonometry skills. We have the opposite side (31.9m) and the adjacent side (55m). To find the angle of elevation, we can use the tangent function.
So, the tangent of the angle of elevation is equal to the opposite side divided by the adjacent side. Therefore, the tangent of our angle is 31.9m/55m.
Now, if we input this into a calculator, we find that the angle of elevation is approximately 31.44 degrees.
Voila! The angle of elevation of the flagpole is approximately 31.44 degrees. Keep in mind though, I can't vouch for the accuracy of my calculations, so take it with a grain of circus salt!
To find the angle of elevation of the flagpole's top, we can use trigonometry.
In this case, we can consider the flagpole's height as the opposite side (O) and the distance from the flagpole as the adjacent side (A).
Given that O = 31.9m and A = 55m, we can use the tangent function to find the angle of elevation. The tangent of an angle is equal to the ratio of the opposite side to the adjacent side.
So, tan(angle) = O/A
Substituting the given values, we get:
tan(angle) = 31.9/55
Now, we can find the angle by taking the inverse tangent (arctan) of both sides:
angle = arctan(31.9/55)
Using a calculator, we find that the angle of elevation is approximately 30.73 degrees.
To find the angle of elevation of the flagpole's top from a point on the ground, we can use the tangent function.
The tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
In this problem, the height of the flagpole represents the side opposite the angle of elevation, and the distance from the point on the ground to the base of the flagpole represents the side adjacent to the angle.
Here's how you can find the angle of elevation:
1. Sketch a right triangle with the flagpole as the vertical side, the distance on the ground as the horizontal side, and the hypotenuse connecting the top of the flagpole to the point on the ground.
2. Use the tangent function to find the angle of elevation:
tangent(angle) = height of flagpole / distance on the ground
tangent(angle) = 31.9m / 55m
3. Use inverse tangent (also known as arctan or atan) to find the angle:
angle = arctan(31.9m / 55m)
Use a scientific or graphing calculator to calculate the inverse tangent of the above ratio. The calculator should provide an output in radians or degrees, depending on the setting.
4. The output will be the angle of elevation of the flagpole's top from the given point on the ground. Make sure to convert the result to degrees if it is given in radians or vice versa if needed.
