A flagpole cast a 20-foot shadow on the ground perpendicular to its base. The angle of elevation from the end of the shadow to the top of the flagpole is 30 which measurement is closest to the height, in feet of the flagpole

Respuesta :

20^2 + b^2 = 30^2

400 + b^2 = 900
-400. -400
Square root b^2 = square root 500

B = 22.36068



X = 22.36068

The distance between the pole flag and the endpoint of the shadow is  22.36 feet.

What is trigonometry?

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

A flagpole cast a 20-foot shadow on the ground perpendicular to its base.

The angle of elevation from the end of the shadow to the top of the flagpole is 30 feet.

By the Pythagoras theorem, we have

[tex]\rm H^2 = P^2+B^2[/tex]

The base is given as

[tex]\rm B^2= H^2 - P^2\\\\B^2 = 30^2 - 20^2 \\\\B^2 = 900 - 400\\\\B^2 = 500 \\\\B \ \ =22.36[/tex]

Thus, the distance between the pole flag and the endpoint of the shadow is  22.36 feet.
