You have to find all the angles first, the first with law of sines and the second with the triangle sum theorem (i think I just made up that name). That is, angle C=180-A-B. You don't want a spoonfed answer so I'll stop here. Make sure you start with law of sines!

Law of Sines, Trigonometry of Triangles - mathwarehouse

WebUsing the Law of Sines, solve for all triangles with ∠A=50∘,a=109, and.b=47. How many triangles fit the given data? If there is one triangle, enter its data below. If there is more than one triangle, pick one and enter its data. If there are no triangles which match the given data, enter DNE in each entry blank below. ∠B ∠C c= Webh = bsin α and h = asin β. We then set the expressions equal to each other. bsin α = asin β ( 1 ab)(bsin α) = (asin β)( 1 ab) Multiply both sides by 1 ab. sin α a = sin β b. Similarly, we … cream color paint for exterior house
