Answer:

x=3

Step-by-step explanation:

5(2x -3) = 15

10x-15=15

10x-15+15=15+15

10x=30

To find the x divide 10 to 30 so that is why 30÷10=3.

You are sitting at the edge of the Grand Canyon admiring the view when you notice a tour group at the bottom of the canyon. You

ololo11 [35]

Answer:

7949.13 feet

Step-by-step explanation:

We are given that,

Angle of depression from the spot to the group = 39°

Height of Grand Canyon = 5000 feet.

So, we will get the following figure of a right triangle.

<em>As, 'in a right triangle, the angles and the sides can be written in trigonometric form'.</em>

We get, $\sin A=\frac{perpendicular}{hypotenuse}$

i.e. $\sin 39=\frac{5000}{x}$

i.e. $x=\frac{5000}{\sin 39}$

i.e. $x=\frac{5000}{0.629}$

i.e. x = 7949.13 feet

Thus, the line of sight distance is 7949.13 feet.
