Find length of triangle sides given angles
WebHere, we want to order the angles of the triangle from smallest to largest, and we're given the sides. Well, same, exact idea. The smallest angle is going to be opposite the smallest side or the shortest side. Well, the shortest side is this side of length 7.2. The angle that opens up onto it is angle a. WebFirst find angle X by using 'angles of a triangle add to 180°': X = 180° − 87° − 42° = 51° Now find side y by using the Law of Sines: y sin (Y) = x sin (X) y sin (87°) = 18.9 sin (51°) y = sin (87°) × 18.9 sin (51°) y = 24.29 to 2 decimal places. Similarly we can find z by using the Law of Sines: z sin (Z) = x sin (X) z sin (42°) = 18.9 sin (51°)
