Try this out! Using the figure below, write expression that gives the required unknown value. 1. If \( \mathrm{A}=15^{\circ} \) and \( c=37 \), find \( a \). 2. If \( \mathrm{A}=76^{\circ} \) and \( a=13 \), find \( b \). 3. If \( \mathrm{A}=49^{\circ} \) and \( a=10 \), find \( c \). 4. If \( a=21.2 \) and \( \mathrm{A}=71^{\circ} \), find \( b \). 5. If \( a=13 \) and \( \mathrm{B}=16^{\circ} \), find \( c \). 6. If \( \mathrm{A}=19^{\circ} \) and \( a=11 \), find \( c \). 7. If \( c=16 \) and \( a=7 \), find \( b \). 8. If \( b=10 \) and \( c=20 \), find \( a \). 9. If \( a=7 \) and \( b=12 \), find \( A \). 10. If \( a=8 \) and \( c=12 \), find \( B \),
