Answer 1

Answer:

as we know that the sum of angles of quadrilateral is 360° .Let us suppose the angle b x

Step-by-step explanation:

atq(according to question)

x+2x+4x+5x=360°

12x=360°

x=360/12

x=30°

put x=30 in place of x

x=30°

2x= 30*2

2x=60°

4x=4*30

4x=120°

5x=5*30°

5x=150°

{Check :-

30°+60°+120°+150°=360°

360°=360°.}
