Answer:
16.24°
Step-by-step explanation:
Are you trying to find the angle of depression from the camera to the cashier?
Assume that the camera is 2.24 m high and the cashier is 7.69 m away.
1. Angle of elevation from cashier
tanθ = 2.24/7.69 = 0.2913
θ = arctan(0.2913) = 16.24°
2. Angle of depression from camera
∠ of depression = ∠ of elevation = 16.24°
Answer:
Step-by-step explanation:
Let's call the balloon's height above the ground and
the horizontal distance between the balloon and the first milepost.
If the angle of the depression of this milepost is 24 degrees, we can say the following:
<em>(equation 1)</em>
For the next milepost, the horizontal distance between the balloon and tihs milepost will be and the angle of depression will be 20 degrees, so we can say the following
then, replacing from <em>equation 1</em>
Resolving, we'll find the value of
So, the balloon's height above the ground is 1.99miles
