49. Find the m a. 60°
b. 75⁰
c. 30°
d. 73°

Answer 1

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)`
