Answer:
θ = 
Step-by-step explanation:
Since the vertical height of the mountain is 800 feet, and the distance from the top to its base is 1600 feet. Let the angle of elevation be represented by θ, applying the required trigonometric function;
Sin θ = 
Sin θ = 
= 0.5
θ =
0.5
θ = 
Thus, the angle of elevation from the base to the top of the mountain is
.
Answer:
It is true.
