# From the adjoining figure find $x$,  i $AOB$ is a straight line. Hence complete the following Which is an acute angle?

##### SOLUTION
R.E.F image
now ,we know
$\angle POA+\angle POB=180^{\circ}$
$x+10+x-10=180^{\circ}$
$2x= 180^{\circ}$
$[x=90^{\circ}]$
NOW $\angle POB=90+10=80$
& $\angle POA=90+10=100^{\circ}$
$\angle$ POB is acute angle. You're just one step away
