From a distance of 42 feet from the base of a building, the angle of elevation to the top of the building is 67°. Estimate the height of the building to the nearest foot

Respuesta :

Answer:

The height of the building to the nearest foot is 99 feet.

Step-by-step explanation:

Height of the building , p= x

Distance between the base of the height from where angle of elevation is 67° = b = 42 ft

According trigonometric ratios:

[tex]\tan \theta =\frac{p}{b}[/tex]

[tex]\tan 67^o=\frac{x}{42 ft}[/tex]

(tan 67° = 2.3558)

[tex]x=2.3558\times 42 ft=98.94 ft\approx 99 ft[/tex]

The height of the building to the nearest foot is 99 feet.
