# The measure of an angle which is four times its supplement is

$144^o$

##### SOLUTION
Option (b) is correct.
Let $y$ be the angle and its supplement is $180^o -y$
$ACQ$,
$\Rightarrow y=4(180^o -y)$
$\Rightarrow y=720^o -4x$
$\Rightarrow 720^o =5y$
$\Rightarrow y=\dfrac{720^o}{5}$
$\Rightarrow y=144^o$
