Find x the angle of depression from the top of a lighthouse that is 184 ft above water level to the waterline of a ship 970 off shore.
Round your answer to the nearest tenth of a degree.
:
We can find the interior angle (A) that is associated with the angle of depression using the tangent
tan(A) = 970%2F184
A = 79.3 degrees
therefore
90-79.3 = 10.7 degrees is the angle of depression

Answer:

The answer to your question is: Ф = 81.1° = 278.9°

Explanation:

Data

angle, x, = ?

height = 170 ft

distance 1084 ft

Process

tan Ф = opposite side / adjacent side

tan Ф = 1084 / 170 = 6.37

Ф = tan ⁻¹ (6.37)

Ф = 81.1° or 360 - 81.1 = 278.9°

** URGENT** The voltage across the primary winding is 350,000 V, and the voltage across the secondary winding is 17,500 V. If th
Vlad [161]

As we know that in transformers we have

\frac{V_s}{V_p} = \frac{N_s}{N_p}

here we know that

V_s = 17,500 Volts

V_p = 350,000 Volts

N_s = 600 coils

now from above equation we will have

\frac{17500}{350000} = \frac{600}{N_p}

N_p = 600\times \frac{350000}{17500}

N_p = 12000 coils

What happens to the gravitational attraction between 2 objects
amm1812

Answer:

It decreases.

Explanation:

between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases
