<u>Answer:</u>
<u>Step-by-step explanation:</u>
The sum of interior angles of a quadrilateral is 360°.
If we consider the measure of one of the unknown angles to be °, we can set up the following equation:
Now we can solve for :
⇒
⇒ [subtracting 192° from both sides]
⇒
⇒ [dividing both sides by 2]
⇒
Therefore, the other two angles each have a measure of 84°.
