Thats a proportion. i'll show you the formula that is easier to solve with that is more universal and you can try to see how it relates to that one seeing as this topic is VERY important.

You know that 20%=.2

Let x be the number

.2x=50

x=250

If you need more help still just tell me.

Given

$Side\ 1 = 4$

$Side\ 2 = 5$

$Side\ 3 = 10$

Do they form a triangle

To check if they form a triangle or not, we make use of trinagle inequality theorem which states that; for sides a, b and c

$a + b > c$

$a + c > b$

$b + c > a$

So for sides 4, 5 and 10, we have:

$4 + 5 > 10$ --- False

$4 + 10 > 5$

$5 + 10 > 4$

<em>Since the one of the inequalities is false, then the sides do not form a triangle.</em>

Help! I need help with finding the value of x.

Dmitry_Shevchenko [17]

Answer:

x = 18.64

Step-by-step explanation:

use tan:

⇒ tan = $\frac{opposite}{adjacent}$

⇒ tan 46 = $\frac{18}{x}$

tan of 46 is 1.0355

⇒ 1.0356 = $\frac{18}{x}$

multiply 18 on both sides

⇒ 1.0355 x 18 = $\frac{18}{x}$ x 18

⇒ 18.64 = x
