b. Tan 27 = (h+L)/500.
L = Length of flag = ?
h = Ht. of bldg. calculated in part a.
High appreciate
To solve this problem, we will use basic trigonometry principles. Let's start by labeling the given information:
Distance from the observer to the building's base = 500m
Angle of elevation to the top of the building = 24 degrees
Angle of elevation to the top of the flagpole = 27 degrees
First, let's find the height of the building:
1. We can use the tangent function to find the height of the building. The tangent of an angle is equal to the opposite side divided by the adjacent side.
2. In this case, the opposite side is the height of the building, and the adjacent side is the distance from the observer to the building's base.
3. So, we can write the equation as follows: tan(24 degrees) = height of the building / 500m.
4. Rearranging the equation to solve for the height of the building: height of the building = tan(24 degrees) * 500m.
Now, let's find the length of the flagpole:
1. We can use the same principle as before. The tangent of the angle of elevation to the flagpole is equal to the opposite side (height of the building + length of the flagpole) divided by the adjacent side (distance from the observer to the building's base).
2. So, we can write the equation as follows: tan(27 degrees) = (height of the building + length of the flagpole) / 500m.
3. Simplifying the equation: length of the flagpole = tan(27 degrees) * 500m - height of the building.
Now we can substitute the values into the equations:
Height of the building = tan(24 degrees) * 500m
Length of the flagpole = tan(27 degrees) * 500m - height of the building
Calculating these values will give us the height of the building and the length of the flagpole.
