Question 49


(\sin C)/(c)=(\sin B)/(b)\\\\\sin C=(c \sin B)/(b)\\\\C=\arcsin \left((c \sin B)/(b) \right)\\\\C=\arcsin \left((17 \sin 47^(\circ))/(13) \right)\\ m \angle C \approx 73^(\circ)

Question 50


\cos T=(22^2+24^2-16^2)/(2 \cdot 22 \cdot 24)\\\\T=\arccos \left((22^2+24^2-16^2)/(2 \cdot 22 \cdot 24) \right)\\\\T \approx 40.5^(\circ)
