Answer:The sum of first angle second angle =150

⇒ The ratio of third and fourth angle is 2:3

⇒ Let third angle fourth angle be 2x and 3x.

Step-by-step explanation:

150 +2x+3x=360

⇒ 5x=210

⇒ x=42

⇒ Now, 2x=2×42

=84

⇒ 3x=3×42

=126

⇒ The measure of two angles are 84

and 126

Step-by-step explanation:

Sum of angles of quadrilateral = 360 degree

so 210+20+6x+7x = 360

230+13x= 360

13x= 360-230=130

x= 130/13=10

so third angle =6x= 6*10=60 degree

and 4th angle= 7x= 7*10=70 degree
