# If in any ∆ABC, < We know in a triangle,

A + B + C = 180°

A = 180° - B - C

Substituting the given values, we get

A = 180° - 45° - 105°

A = 30°

Let a, b, c be the sides of the given triangle. Then by applying the sine rule, we get  Now substituting the corresponding values we get Substitute the equivalent values of the sine, we get   Hence the value of b is 2√2 units.
