Since arc ST  = 170   and arc  QR  =  110

Then the sum  of  arcs  TR and SQ =  360 - 170 - 110  =  80

And

Measure of P  =  (1/2)(arc TR - arc SQ)

30  = (1/2) (arc TR - arc SQ)    multiply both sides  by  2

60  = arc TR  - arc SQ

So   we have these equations

arc TR  + arc SQ =   80

arc TR -  arc SQ  = 60         add these

2arc TR   =  140     divide both sides by  2

arc TR   = 70°
