Hint: Try using angles and line measures (and some geometric intuition) to find the ratio of ET to TC

 

Extra hint: (congruent triangles/similar triangles?)

 

Even more extra hint: Look at triangles EST and TRC

 

Even even more extra hint: How do we find out what shape SDRQ is?

 

(If you still need help, just ask me!)

***Arc  SR is not 106º ***      it's  117.52º   ( you don't need it, anyway)

 

Since the points S, T, and R are tangent points, we have:

 

         ET = SE = 26        |         SD = DR = 32        |       RC = TC = 48

                 ( 26                +                 32                 +                48 ) * 2  = Perimeter  wink
