A person is standing on a cliff that is 200ft above a body of water. The person looks down at an angle of depression of 42o at a
velikii [3]

Answer:

524.5 feet

Step-by-step explanation:

Given: Height of cliff= 200 ft

           Angle of depression at sail boat is 42°

           Angle of depression at yacht is 15°

Lets assume distance sailboat from the bottom of cliff is "d_1"

And assume distance yacht from the bottom of cliff is "d_2"

Now using tangent rule to solve it.

we know, tan\theta = \frac{opposite}{adjacent}

Distance sailboat from the bottom of cliff; tan 42= \frac{200}{d_1}

Using trignometry table to know the value of tan 42°

⇒0.90= \frac{200}{d_1}

cross multiplying both side.

⇒ d_1= \frac{200}{0.90} = 222.22 \approx 222

∴ Distance sailboat from the bottom of cliff (d_1)= 222 feet

Distance yatch from the bottom of cliff; tan 15= \frac{200}{d_2}

Using trignometry table to know the value of tan 15°

⇒0.2679= \frac{200}{d_2}

cross multiplying both side.

⇒ d_2= \frac{200}{0.2679} = 746.54 \approx 746.5

∴Distance yacht from the bottom of cliff (d_2)= 746.5 feet.

Next, finding the distance between sailboat and yacht.

Distance between sailboat and yacht = d_2-d_1

⇒ Distance between sailboat and yacht= 746.5-222= 524.5\ ft

∴ Distance between sailboat and yacht is 524.5 feet.

If a line crosses the y-axis at (0, -3) and has a slope of 3, what is the equation of the line?
Semenov [28]
General equation of the line is 
y = mx + c

c = -3
m = 3

so the equation is
y = 3x - 3
