gotcha

OpenStudy (driftracer305):

can't see the options clearly.....

OpenStudy (aum):

If from an external point you draw two tangents to a circle, then the tangents will be of equal lengths.

OpenStudy (anonymous):

There is a 146

OpenStudy (driftracer305):

can you list all your options please.....just in case

OpenStudy (driftracer305):

yea...sorry it is 146....... just calculated 3 times.... all good

OpenStudy (anonymous):

Thanks!

OpenStudy (driftracer305):

no prb......

jimthompson5910 (jim_thompson5910):

we're given this

jimthompson5910 (jim_thompson5910):

based on what aum pointed out (about the congruent tangents), we can then determine this

jimthompson5910 (jim_thompson5910):

so we have these 3 sides in red

jimthompson5910 (jim_thompson5910):

Those three red sides add to 53+52+41 = 146
