wolf1728 · Answer

arc length = radius * central angle (in radians)
RTS is an inscribed angle  
angle O is the central angle 
Angle RTS is exactly 1/2 of the central angle.
The problem starts that the LENGTH of arc RS is 64 degrees.  Shouldn't a length be stated in linear measure and not in angular measure?
Due to the 64 degree arc, I can't work anymore on this problem/

Does it mention whether chords RT = ST ?

96mertcank96 · Answer

nope

hero · Answer

Are there any tic marks through RT and ST?

96mertcank96 · Answer

nope i showed everything thats on the question

hero · Answer

You can at least find the length of arc STR

arc STR = 360 - 64 = 360 - 60 - 4 = 300 - 4 = 296

96mertcank96 · Answer

what can i do from there?

hero · Answer

If we assume RS = ST, then arc TS = 296/2

96mertcank96 · Answer

would you consider rts to be centered?

hero · Answer

so arc TS = 148

arc RST = 148 + 64

hero · Answer

O is the center
