Answer:

A) 9

Step-by-step explanation:

First you need to find the measure of angle c

Since it's a quadrilateral, the interior angles add up to 360 degrees

Now there's two right angles and one 99 degree angle

Add those and subtract from 360

360 - (90+90+99) = 81

C = 81 degrees

However x is the root of c so root 81 is 9
