3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

is only a line? i think so

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.
