You have the next measures of angles:

$m\angle\text{ZFDE}=(3x-15)$
$m\angle ZFDB=(5x+59)$

And you need to find the value that makes the angles supplementary. It means that you need to find the value of x that makes that: the sum of the angles has to be 180º

$m\angle ZFDE+m\angle ZFDB=180º$

Then you have:

You clear the x, as follow:

Then so, the value of x that makes that ZFDE and ZFDB are supplementary is x=17

If mZFDE = (3x – 15) and mZFDB = (5x + 59)", find the value of x such that ZFDE-example-1

If mZFDE = (3x – 15) and mZFDB = (5x + 59)", find the value of x such that ZFDE-example-2
