A forest ranger stands at the top of a 120 foot fire tower. He spots a fire 900 feet away from the base of the tower. What is th

allochka39001 [22]

Answer: $7.6\°$

Step-by-step explanation:

You need to draw a right triangle as the one attached, where $\alpha$ is the angle of elevation from the fire to the top of the fire tower.

You need to use the Inverse trigonometric function Arctangent:

$\alpha= arctan(\frac{opposite}{adjacent})$

Observe the triangle. You can identify that:

$opposite=120\\adjacent=900$

Then, you can substitute values:

$\alpha= arctan(\frac{120}{900})$

Finally, evaluating, you get that the angle of elevation from the fire to the top of the fire tower is the following:

$\alpha =7.59\°$

Rounded to the the nearest tenth of a degree:

$\alpha\approx7.6\°$

Find the equation for the line shown on the right.

erastova [34]

Answer:

$x = 8$

Step-by-step explanation:

Given

See attachment for graph

Required

The line graph

First, consider the following points on the graph.

$(x_1,y_1) = (8,0)$

$(x_2,y_2) = (8,8)$

First, calculate the slope.

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{8-0}{8-8}$

$m = \frac{8}{0}$

$m =$ undefined

Since, the slope is undefined; we simply consider only the value of x.

The line equation is:

$x = 8$
