The value of x is 100 where AOB is a straight line and 4x=5y
Step-by-step explanation:
AOB is a straight line
=> ∠AOC + ∠BOC = 180°
∠AOC = y
∠BOC x
=> y + x = 180°
=> y = 180° - x
now given that
4x = 5y
Putting value of y in ths
=> 4x = 5(180° - x)
=> 4x = 5 * 180° - 5x
=> 9x = 5 * 180°
=> x = 5 * 20°
=> x = 100°
The value of x is 100
