Answer 1

use sin law, which is valid for all trianglesm:

\[\frac{ sinA }{ a } = \frac{ sinB }{ b } = \frac{ sinC }{ c }\]



notice that the letter of the side corresponds with the letter of the angle opposite to it.

Answer 2

so were dealing with side 'b' and side 'a' and the corresponding angles 'B' and 'A' respectively.

\[\frac{ \sin110 }{ b } = \frac{ \sin20 }{ a }\]
\[\frac{ \sin110 }{ \sin20 } = \frac{ b }{ a }\]
which by calculator gives:

\[2.747 = \frac{ b }{ a }\]

since the left side is > 1, this means that b is larger than a
