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°
Hope it will helps you
