In the given figure, it is given that $AOB$ is a straight line and $4x=5y$. What is the value of $x$ ?

$100$

SOLUTION
(a) $100$
Because,
Let the measure of its supplement be $4x$ and $5y$.
Then,
= $x + (4/5)x$ = $180^{o}$
= $(5x + 4x)/5$ = $180$
= $9x$ = $180\times 5$
= $9x$ = $900$
= $x$ = $900/9$
= $x$ = $100$
