Answer:

115.02 feet

Step-by-step explanation:

The angle of depression from an air traffic control tower to an airplane on the runway is 72 degrees. If the tower is 354 feet tall, how far is the airplane from the base of the tower?

We solve this question using the Trigonometric function of tan

tan x = Opposite/Adjacent

x = Angle of depression = 72°

Opposite = Height of the tower = 354 feet

Adjacent = Distance of the airplane from the base of the tower = y

Hence,

tan 72 = 354/y

Cross Multiply

tan 72 × y = 354

y = 354/tan 72

y = 115.02157247 feet

Approximately = 115.02 feet

Therefore, the distance of the airplane from the base of the tower is 115.02 feet

What can be concluded if angle 1 =angle7
Maksim231197 [3]

From the information given in the question,
the only possible conclusion is:

              If angle 1 is measured and angle 7 is measured,
           the two measurements will be identical.

If angle 1 and angle 7 are related to a particular shape or drawing,
then additional conclusions may be possible, but we'd need to see
the shape or drawing.

How would you do these questions?
Pepsi [2]

Step-by-step explanation:

1. P(light OR domestic) = P(light) + P(domestic) − P(light AND domestic)

P(light OR domestic) = 0.62 + 0.70 − 0.55

P(light OR domestic) = 0.77

2. P(light AND not domestic) = P(light) − P(light AND domestic)

P(light AND not domestic) = 0.62 − 0.55

P(light AND not domestic) = 0.07

3. P(light GIVEN not domestic) = P(light AND not domestic) / P(not domestic)

P(light GIVEN not domestic) = 0.07 / (1 − 0.70)

P(light GIVEN not domestic) = 0.233

4. Two events are independent if P(A) × P(B) = P(A and B).

P(light) × P(domestic) = 0.62 × 0.70 = 0.434

P(light AND domestic) = 0.55

Therefore, the type and location are not independent.
