Question

determine the value of x. hence find angle aob , cod , doe.​

Answer 1

Step-by-step explanation:

5x + 6x + 4x + 90 + 30=360 ( complete angle)

15x + 120 = 360

15x= 360-120

15x= 240

x=240/15

x=16

now,

AOB=96

COD=64

DOE=80

Answer 2

Answer:

4x° +30°+6x°+5x°+90° = 360° (sum of complete angle)

15x° = 360°-120° = 240°

x° = 16°

Angle AOB = 6x° = 6× 16 = 96°

angle COD = 4x° = 4× 16 = 64°

angle DOE = 5x° = 5× 16 = 80°
