Question
solve each triangle using either the Law of Sines or the Law of Cosines.$$B=35^{\circ}, C=65^{\circ}, a=15$$
Step 1
We can find the third angle A using the property that the sum of all angles in a triangle is 180 degrees. So, we have: $$ A = 180^{\circ} - B - C = 180^{\circ} - 35^{\circ} - 65^{\circ} = 80^{\circ} $$ Show more…
