Question

In the figure, find x. Further, find angle AOC, angle COD and angle BOD.
Please anybody who know tell plz tomorrow is my exam of class 9th. ​

Answer 1

Step-by-step explanation:

<AOC + <COB = 180° ( LINEAR PAIR)

<AOC + <COD + < DOB = 180°. [<COB = <COD +< DOB]

3x +6 + 2x -18 + x = 180

6x -12 = 180

6x = 180 + 12

6x = 192

x = 192 /6

x = 32.

so,

<AOC = 3(32) +6

= 96 +6

= 102°

< COD = 2(32) -18

= 64 -18

= 46°

<DOB = 32°.
