Answer 2

Value of x is 35°

Step-by-step explanation:

We know that sum of all angles of a straight line is equal to 180°....

Now,

Angle AOD + Angle DOC + Angle COB = 180°

=> ( x-10° ) + ( 4x-25° ) + ( x+5° ) = 180°

=> x-10° + 4x-25° + x+5° = 180°

=> 6x - 30° = 180°

=> 6x = 180° + 30°

=> x = 210°/6

=> x = 30°

Therefore,

Angle AOB = x-10° = 35°-10° = 25°

Angle DOC = 4x -25 = 140°-25° = 115°

Angle COB = x+5° = 40°
