For a person standing 100m from the center of the base of the excel tower, the angle of elevation to the top of the tower is 71.
Crazy boy [7]

Answer:

Given the statement: For a person standing 100 m from the center of the base of the excel tower, the angle of elevation to the top of the tower is 71.6 degrees.

Let h be the height of the Eiffel tower.

Angle of elevation is, \theta =71.6^{\circ}

Distance of boy standing from the center of the base of the Eiffel tower is, 100 m.

Using tangent ratio:

\tan \theta = \frac{\text{opposite side}}{\text{Adjacent side}}

From the given figure as shown;

Solve for h;

\tan 71.6 = \frac{h}{100}

Multiply both sides by 100 we have;

h = 100 \tan 71.6

or

h = 100 \times 3.0061109035

Simplify:

h \approx 300 m

therefore, the height of the Eiffel tower is, 300m
