For [math]\triangle ABC[/math], find the measure of angle [math]C[/math] if [math]m\angle A = 34^\circ[/math], [math]c = 9[/math] meters, and [math]a = 7[/math] meters.
[list=1] [*]Substitute the known values into the Law of Sines. [*]Determine which two fractions are necessary for solving the equation and then solve. [*]Use your calculator to find [math]m\angle C[/math]. [*]Determine whether the ambiguous case is possible to determine if there is a second valid answer. [*]Determine the second valid measure of angle [math]C[/math]. [/list] This applet is provided by Walch Education as supplemental material for the [i]UCSS Secondary Math III[/i] program.
