Answer 1

Answer 2

Step-by-step explanation:

Let the angles be x.

Therefore, we know that the sum of all the four angles of a quadrilateral is 360°.

So,

3x + 7x + x + 7x = 360

18x = 360

x = 360/18

x = 20

Now,

first angle,3x= 3 × 20 = 60°.

second angle,7x= 7×20=140°.

third angle,x= 20°.

fourth angle, 7x=140°
