Answer:
<h2>24° , 72° , 108° , 156°</h2>Step-by-step explanation:

We know that the sum of quadrilateral is 360°
Now,
Calculate the sum
Divide both sides of the equation by 30
Calculate
Replacing the value,
2x = 2 * 12 = 24°
6x = 6 * 12 = 72°
9x = 9 * 12 = 108°
13x = 13 * 12 = 156°
So, the angles are 24° , 72° , 108° , 156°
