Question

given rectangle opqr below. if ( mangle rso = 112^circ ), find ( mangle qsr ).
answer attempt 1 out of 10
( mangle qsr = )
submit answer

Explanation:

Step1: Identify supplementary angles

$\angle RSO$ and $\angle QSR$ are supplementary (they form a straight line, so their sum is $180^\circ$).

Step2: Calculate $\angle QSR$

Subtract $\angle RSO$ from $180^\circ$.
$m\angle QSR = 180^\circ - m\angle RSO$
$m\angle QSR = 180^\circ - 112^\circ$

Answer:

$68^\circ$
