a.
To find: The height of the flagpole to the nearest foot.
The height of the flagpole is
Given:
The figure is given below:
Where the angle of elevation of the sun was
Calculation:
Here, the height of the flagpole
Hence, the height of the flagpole is
b.
To determine the length of the shadow when the angle of elevation of the sun was
The length of the shadow is
Given:
The figure is given below:
Calculation:
The length of the shadow
Hence, the length of the shadow is
a.
To find: The assuming quantity for the flagpole and the shadow to solve the problems.
Angle of elevation of the sun
Interpretation:
Here, the problem can be solved if the angle of elevation of the sun is assumed.
With respect to the angle, the length of opposite and adjacent legs can be found using tangent function.
