n! / r! (n – r)!

9! / 3! (9 – 3)!=

9! / (3! * 6!)=

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;

$h = 100 \tan 71.6$

$h = 100 \times 3.0061109035$

Simplify:

$h \approx 300 m$

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