What does the work look like first
Answer:
<h2>x = 117°</h2>
Step-by-step explanation:
We know:
The sum of the quadrilateral angles measures 360°.
Therefore we have the equation:

The sum of angles x and D is equal to 360°. Therefore we have the other equation:

From (1) and (2) we have:

You basically need to set up a porporion:
1.6/2.4 = x/7.2
x=4.8
