Answer:

The angle of depression between the cliff  and the boat is 48.8141^\circ

Step-by-step explanation:

Given:

Base width  of the cliff=175 foot

Height of the cliff= 200 foot= 200 foot

To Find:

The angle of depression between the cliff  and the boat=?​

Solution:

Angle of Depression

The angle below horizontal that an observer must look to see an object that is lower than the observer.The angle of depression is congruent to the angle of elevation  

tan( y )= \frac{opposite}{adjacent}

Substituting the values,

tan( y )= \frac{200}{175}

tan( y )= 1.14

y= tan^{-1}(1.14)

y=48.8141^\circ

A. The point-slope form of the equation of a line is y ? y1 = m(x ? x1), where m is the slope and (x1, y1) is a point on the lin
Rudiy27

Answer:

A.

y - 5 = -2(x-6)

Negative reciprocal gives you the perpendicular slope so negative reciprocal of 1/2 is -2.

Then apply point-slope form.

B. The answer is x = 6.

The midpoint of JK is

\left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) = \left( \frac{8+ 4}{2}, \frac{4 + 4}{2} \right) = \left(6,4\right)

The line that goes through JK is just a horizontal line y = 4 because the y-coordinate does not change. So its perpendicular bisector is the vertical line that goes through the x-coordinate of the midpoint, that is, x = 6.
