Two sides and an angle are given. Determine whether the given information results in one triangle, two triangles, or no triangle. Solve any triangle that result

Question

Side a = 26; Side b = 20; 

Angle B = 15 degrees 

Answer 1

 b/ SinB = a/ SimA

 

 

20/ Sin 15° =26 / Sin A

 

 

  A = Sin ^-1 ( 26 * Sin( 15°) )/20 = 19.66°

 

  C = 180 - ( 15 + 19.66) = 145. 34

 

   c/ Sin 145.34° = 20/ sin15°

 

   c = 20 * Sin 145.34° / Sin 15° = 43.95
