Apark ranger at the top of a 700-meter station sees a fair that is 1800 meters from the base of the tower.

what is the angle of elevation in degrees?

The angle of elevation is 20.806°   .

Step-by-step explanation:

Given as :

The height of the station = 700 meter

The distance from the base of tower = 1800 meter

Let the angle of elevation = Ф

Now,

∵ Tan Ф =

So,  Tan Ф =

Or, Tan Ф =

Or, Tan Ф = 0.38

∴   Ф =

I.e   Ф = 20.806°

Hence The angle of elevation is 20.806°   . Answer

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
