Step-by-step explanation:
From the question we are told that:
Arc
Arc
Given The angle of intersecting chords theorem
Generally the equation for angle BEC is mathematically given by



Answer:
<h3>8.5 degrees</h3>
Step-by-step explanation:
The set up will give a right angles triangle;
Given
The height of the ramp (opposite) = 6 foot
distance away along the ground = 40 feet (adjacent)
Required
Angle of depression theta
Using the TOA identity;
tan theta = opposite/adjacent
tan theta = 6/40
tan theta = 0.15
theta = tan^-1{0.15}
theta =8.53 degrees
hence the angle of depression to nearest tenth of a degree is 89.5 degrees
10 would be my best bet. Hope this helps.
