Question

if Aob is a straight line and 4x = 5y the value of x is ? ​

Answer 1

Answer:

x=100

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
