Answer:
360-270=x
x=90 degrees
Step-by-step explanation:
There are two ways i know of how you can do this
<em>The first way:</em>
Ok so lets add up all the angles we know
<u><em>90+90+90=270</em></u>
Now we subtract that from 360
<u><em>360-270=90</em></u>
And there we have it the measure of angle x is 90 degrees
<em>The second way:</em>
Ok lets name all the angles we know. Hypothetically we only know that one angle is 90.
<u><em>measure of angle one is 90 degrees</em></u>
So now we subtract that from 360
<u><em>360-90=270</em></u>
Now we divide that by three because there are only 4 angles and we know the measure of one of the angles
<u><em>270/3=90</em></u>
And there we have it the measure of angle x is 90 degrees
