Answer:
The correct answer ∠RSC
Step-by-step explanation:
From the given information, we get a triangle ΔQRS
<SQR and < QRS are two interior angles of triangle QRS
Other interior angle is <QSR,
Therefor m<QSR = 180 - (sum of other 2 angles)
m<QSR = 180 - (m<SQR + m<QRS) (angle sum property)
And also, m<RSC = 180 - m<QSR
Therefore <RSC = (m<SQR + m<QRS)
