There are three basic things you need to know to solve a triangle. 1st. The sum of all the angles of a triangle equals 180° or n 2nd. The law of sines is useful when we have at least two angles of a triangle. Build a proportion that includes three known and one unknown quantity (sometimes it must be done is steps, or repeated twice) sin(A) sin(B) sin(C) a des, or 3rd. The law of cosines is useful when we have an angle of a triangle and two all sides only and no angle. a = 62 + c - 2bc cos(A) a? + c2 2ac cos(B) %3D - vwwン) As shown in the figure below, angle A is opposite side a, angle Bis opposite side b, and angle Cis opposite side c.
