Note 

 

sin 23  =  cos(90 - 23)   =  cos (67°)....so x  = 67

 

The second one seems trickier than it really is

 

RP....note that

 

sin P  =  cosR       and

cos P  =  sin R

 

so

 

Sin R  - cos R   =

 

Cos P  - Sin P  =   .8192   - . 5736  =   0.2456

 

Edit to correct a previous mistake  !!!

cool cool cool
