Answer:
78.9 degrees to the nearest tenth.
Step-by-step explanation:
This equals the angle whose tangent is 320/62.5 ( opposite side / adjacent side).
The angle of elevation from the coin to the top of the tower
What is angle of elevation?
The angle formed by the line of sight and the horizontal plane for an object above the horizontal.
Given that:
The coin lands 62.5m away from the center of the base of the 320m- high structure.
Height= 320 m
Base= 62.5 m
Now, tan [tex]\theta[/tex] = [tex]\frac{P}{B}[/tex]
=[tex]\frac{320}{62.5}[/tex]
= 5.12
[tex]\theta[/tex]= [tex]tan^{-1} (5.12)[/tex]
[tex]\theta[/tex]= [tex]78.94^{0}[/tex]
The angle of elevation is: 78.94 degrees.
