# Two angles are supplementary, if one of them is $\displaystyle { 49 }^{ o }$. Find the other angle?

$\displaystyle { 131 }^{ o }$

##### SOLUTION
Since, two angles are supplementary their sum is $\displaystyle { 180 }^{ o }$
$\displaystyle \angle 1+\angle 2={ 180 }^{ o }$
$\displaystyle { 49 }^{ o }+\angle 2={ 180 }^{ o }$ (As one of the angle is $\displaystyle { 49 }^{ o }$
$\displaystyle \angle 2={ 180 }^{ o }-{ 49 }^{ o }$
$\displaystyle ={ 131 }^{ o }$
