Answer 2

Answer:

x° = 80°

Step-by-step explanation:

Given,

Angle AOD = 80°

Angle BOC = 70°

Angle COD = 130°

Angle AOB = x°

We know that,

Sum of Angles at a point is 360°

=> 80°+70°+130°+x° = 360°

=> 280°+x° = 360°

=> x° = 360°-280°

=> x° = 80°

Angle AOB => x° = 80°

Hope it helps you.....
