In ΔJKL, j = 8.1 inches, ∠K=160° and ∠L=14°. Find the length of l, to the nearest 10th of an inch.

Angle  J  =   180  - 160  - 14    =   6°

 

Using the  Law  of Sines

 

J  / sine  of angle J    =  L / sine  of angle  L

 

8.1  / sin 6° =  L  / sin 14°

 

L  =  8.1 sin 14°  / sin 6° =  18.7  inches
