We know :-
A straight angle = 180°
we have :-
• angle COB = 112°
• angle AOC = 4x
and we know
angle AOB = AOC + COB = 180°
→ 4x + 112° = 180°
→ 4x = 180° - 112
→ 4x = 68
→ x = 17°

Question -
In the given figure AOB is a straight line, if Angle BOC = 112° and Angle AOC = 4x, then find x?
Answer -
We know that both the angles are on a straight line , thus forming linear pair .
This problem can be solved using linear pair property . So what we have now is ,
Let's start calculation ,
Now finding the value of angle AOC ,
We have 4x = Angle AOC
Angle AOC = 4 × 17
Angle AOC = 68
Proving the linear pair property with these values ,
According to the linear pair property the angles that lie on the straight line have their sum equal to 180 degree .
Hence proved ✔️
