it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
