Help a girl out plssss and show the work I will literally love u

Answer 1

9

Explanation:

The left side of the triangle is 20 units long, the bottom portion is 8 units long.

This means the top portion must be 12 units long, 20 - 8 = 12.

The ratio between the left and right side has to be the same because they are two straight lines.

So if the ration is 8 to 6 or 8/6 which reduces to 4/3 then your ration is 12 to x.

So if... 4/3x=12 then

(3)4/3x = 12(3) multiply both sides by 3

4x = 36 the divide both sides by 4

x = 9

To check you can multipy your answer, in this case 9 by 4/3.

(9)(4/3) =

(9 x 4)/3 =

36/3 = 12

You did it! Hope this helped.

Answer 2

x=9

Explanation:

`(x+6)/(x) =(20)/((20-8)) \\1+(6)/(x) =(20)/(12) \\(6)/(x) =(20)/(12) -1\\(6)/(x) =(20-12)/(12) \\(6)/(x) =(8)/(12) \\8x=6 * 12\\8x=72\\x=(72)/(8) =9\\x=9`
