Solve the triangle. Express the results to two decimal places.

b = 408, α = 52°42′, β = 75°36′


Please do put solutions so I can understand on how you do it.

A picture is not needed. Determine the size of the third angle and use Law of Sines to calculate missing two sides.

Good, Determine size of angle γ, 180° - α - β. Use the Law of Sines to determin a and c. γ = 180° - (52°42′ + 75°36′) = 52°42′. α = 52°42′, β = 75°36′, γ = 52°42′. a = ??, b = 408, c = ?? Now, for me to use use Law of Sines, tell me which angle belongs to which side. Assume? Angles: <A, <B, <C are not given; instead given α, β, γ; which we don't know their relationship to sides a, b, c
