To find the perimeter of triangle EDC you need ED + DC + CE
ED = 58, DC = 80
You can get EC by adding ET and TC. ET = 26
We need TC

Since ET = 26, ES = 26.
Since ED = 58, SD = 58 - 26 = 32
Since SD = 32, DR = 32
RC = DC - DR = 80 - 32 = 48
TC = RC = 48
Perimeter = ED + DC + CE = 58 + 80 + 26 + 48 = 212
Answer is C.
