Answer:
26.56 degrees
Explanation:
The set up will give a right angles triangle
Given
The Horizontal distance = Adjacent side = 300ft
The height = Opposite side = 150ft
Using the SOH CAH TOA identity;
tan theta = opposite/adjacent
tan theta = 150/300
tan theta = 1/2
theta = arctan 1/2
theta = 26.56 degrees
Hence the angle of elevation is 26.56 degrees
