Answer:
x = 54.15 meters between the balloons horizontally.
Explanation:
Hence, vertical distance between balloons is 12.8 meters.
y= 61-48.2 = 12.2 m
A right-angle triangle is formed with,
angle θ = 13.3 degrees
opposite (y) = 12.8
adjacent (x) = ?
Now by putting the values in the above equation.
x = 54.15 meters between the balloons horizontally.
Given :
The light rays in the incident ray originate at 20º from the surface.
To Find :
The angle for the incident ray.
Solution :
We know angle of incidence is measured from perpendicular to the surface .
So,
Now, we know by law of reflection :
Angle of reflection = Angle of incident
Therefore, the angle of incident and reflection is 70° each.
