(RON - 284º find all the four angles.​

Answer 1

Step-by-step explanation:

Let the center be O

angleFOD= angleCOE. V.O.A

SO angle FOD is 2y

similarly angleCOA=angle BOD= 3y V.O.A

AND angle AOF=angleEOB=5y. VOA.

all angles add upto 360° ASP

so,

2y+2y+3y+3y+5y+5y=360°

20y=360°

y=360°/20

y=18

so angle FOD AND COA= 2Y=2×18=36°

Angle COA and BOD= 3y=3×18=54°

Angle AOF and EOB=5y=5×18=90°
