Non-right Triangles: Law of Sines · Exercise 18

Assume $α$ is opposite side $a, β$ is opposite side $b,$ and $γ$ is opposite side $c .$ Determine whether there is no triangle, one triangle, or two triangles. Then solve each triangle, if possible. Round each answer to the nearest tenth.

$a = 20.5,$ $b = 35.0,$ $β = 25°$
