Question

Determine the unknown angle measures for the quadrilateral in the diagram. (List your answers, separated by commas, in ascending order) ​

Answer 1

Answer:

The angle measures are;

36,72, 108 and 144

Step-by-step explanation:

Since it is a quadrilateral

the sum of all the interior angles is 360

so, we have that;

4x + x + 3x + 2x = 360

10x = 360

x = 360/10

x = 36

So each of the angles are as follows;

x = 36

4x = 4(36) = 144

3x = 3(36) = 108

2x = 2(36) = 72
