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 pla...
In many cases, however, the triangle in question is not a right one, and we need to get additional knowledge in trigonometry to solve arbitrary (oblique) triangles. Recall that by solving a triangle we mean to find its basic elements — sides and angles, given some of them…...
a = 5.30 to 2 decimal places Now we use the The Law of Sines to find the smaller of the other two angles. Why the smaller angle? Because the inverse sine function gives answers less than 90° even for angles greater than 90°. By choosing the smaller angle (a triangle won't have ...
Similar to the Law of Sines, the Law of Cosines enables the solution of oblique triangles by relating the lengths of sides to the cosine of an angle. Employ your scientific calculator to effortlessly solve oblique triangle problems using this law. 5.3 Solving Problems In...

How do I solve for theta using the Law of Sines? To solve for theta using the Law of Sines, you will need to have two angle measures and one side length of a triangle. Then, you can use the formula sin(theta)/a = sin(alpha)/b to solve for the missing angle measure theta. ...
... the one they ask for when a triangle needs solving!In your solving toolbox (along with your pen, paper and calculator) you have these 3 equations:1. Angles Add to 180°: A + B + C = 180° When you know two angles you can find the third. 2. Law of Sines (the Sine Rule...
