Answer:

$x = 2\sqrt{5}$

Step-by-step explanation:

Given

The attached triangle

Required

Find x

Using the sin function

$sin(\theta) = \frac{Opposite}{Adjacent}$

$sin(30) = \frac{\sqrt{5}}{x}$

Make x the subject

$x = \frac{\sqrt{5}}{sin(30)}$

$x = \frac{\sqrt{5}}{1/2}$

Express as:

$x = \sqrt{5}/1/2}$

$x = \sqrt{5}*2/1$

$x = \sqrt{5}*2$

$x = 2\sqrt{5}$

Answer:

It means that for every 1 unit of time, the equation shows an increase of 8.38 units of distance.

Step-by-step explanation:

Slope is $\frac{rise}{run}$ . Any number that does not have a denominator technically has a denominator of 1. Therefore, your slope is actually $\frac{8.38}{1}$ . That means you have a rise, or the vertical progression, of 8.38 while your run, or your horizontal progression, is 1. For every unit your line travels horizontally, it travels 8.38 units vertically. I hope this makes sense.
