-
If necessary, round angles to the nearest degree and give exact values of side lengths.

A) $\mathrm { B } = 60 ^ { \circ } , \mathrm { C } = 90 ^ { \circ } , \mathrm { b } = 7$
B) no such triangle
C) $\mathrm { B } = 60 ^ { \circ } , \mathrm { C } = 90 ^ { \circ } , \mathrm { b } = 7 \sqrt { 3 }$
D) $\mathrm { B } = 90 ^ { \circ } , \mathrm { C } = 60 ^ { \circ } , \mathrm { b } = 7 \sqrt { 3 }$
