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

13. mathstudent55

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.
