Answer:
I think his age is 39.
Step-by-step explanation:
If Cesar's age was 2 times Rosa's 6 years ago, that means their combined ages 6 years ago was 66. 66 dived by 2 is 33 and 33 plus the 6 years is 39.
ES = ET
and
DS = DR
and
CR = CT ( because each pair are tangents to the circle)
So ES = 31 and Ds = 65-31 = 34
and DR = 34 and CR = 74- 34 = 40.
CT = CR = 40
Therfore the line EC = 31 + 40 = 71
Finally the perimeter = 65 + 74 + 71 = 210 (answer)
