Solve trig equations with multiple angles
WebSolving Trigonometric Equations with Multiple Angles. Sometimes it is not possible to solve a trigonometric equation with identities that have a multiple angle, such as \(\sin(2x)\) or … WebThis is also an AAS triangle. First find angle A by using "angles of a triangle add to 180°": A = 180° − 41° − 105° = 34°. Now find side c by using The Law of Sines: c/sin (C) = b/sin (B) c/sin (41°) = 12.6/sin (105°) c = sin (41°) × 12.6/sin (105°) c = 8.56 to 2 decimal places. Similarly we can find side a by using The Law of ...
