If a flagpole casts a 13ft shadow on the ground when the sun is at 68° angle of elevation, which of the following expressions can be used to determine the height (h) of the flagpole? (Assume the flagpole is at a right angle to the ground.)

A) cot 68° = h/13

B) cos 68° = h/13

C) tan 68° = h/13

D) sin 68° = h/13

Respuesta :

Answer:

tan 68° = h/13 ⇒ answer (C)

Step-by-step explanation:

∵ The length of the shadow is 13 ft

∵ Angle of elevation of the sun is 68°

∴ The height of the flagpole is opposite to the ∠68°

  and the shadow is adjacent to it

∵ The flagpole is ⊥ to the ground

∴ tan 68° = h/13

Answer:

C - tan 68 = h/13

Step-by-step explanation:

just took the test, hope this helps !
