Question

please tell me the anwer if q3​

Answer 1

Answer:

Step-by-step explanation:

AOB Is A Straight Angle = 180°.

Angle AOD + Angle COD + Angle BOC = 180°.

x+10+x+x+20 = 180°.

3x+30 = 180°.

3x = 150°

x = 150/3 = 50°.

Therefore,

Angle AOD = x+10 = 50+10 = 60°.

Angle COD = x = 50°

Angle BOC = x+20 = 50+20 = 70°.

Verification,

60°+50°+70° = 180° = Angle AOB.
