Answer:

Step-by-step explanation:

First you need to get like items on the same side(put the variables on one side and the non-variables on the other). Remember anything you do on one side of the equal, you have to do on the other side, too.

5X+3=7X-1 I'm going to move the -1 first, but you don't have to as long as you keep the equation equal.

5X+3+1=7X-1+1 We know that +1-1 is zero and so is -1+1. So

5X+3+1=7X We don't need to keep that zero.

5X+4=7X Now, we want to move the 5X over.

5X-5X+4=7X-5X Simplify and get rid of the zero.

4=2X Last, we have to divide to get the 2 away from the X.

4/2=2X/2 Not everyone know that slash mean divide, :-).

2=X

A lighthouse keeper has a 10 degrees angle of depression between the horizontal light beam and the line of sight from the ship.

Andrei [34K]

107.75m
This is a trigonometric ratio problem. the angle of depression (10) is opposite the height (19m) and the distance is adjacent to the distance (x). opposite ad adjacent sides to the angle is a tangent problem.
$tan \theta = \frac{opp}{adj}$
plus in values, we know.
$tan (10) = \frac{19}{x}$
switch tan(10) and x using the products property.
$x = \frac{19}{tan (10)}$
plug in to calulator to get answer
x=107.75
