Solve to one decimal place.

A) 15 / sin 43 degrees. = 13 / sinB 
C) sin14 degrees / 3.1 = sin27 degrees / b

A) 15 / sin 43 degrees. = 13 / sinB       rearrange as

 

sin B = 13 sin 43 / 15    =   (13/15)sin43

 

arcsin [ (13/15) sin 43 ]  = B  ≈  36.2°

 

 

 


C) sin14 degrees / 3.1 = sin27 degrees / b        rearrange as

 

b  = (3.1)sin 27/ sin 14  ≈  5.8
