Answer 1

Answer:

please mark my answer brainliest and give thanks to me

Step-by-step explanation:

actually you have put an extra 0

it should be 55 and 110

we know that exterior angles' sum always equals to360 degree

let the unknown angle be x

so,

110+55+x=360

165+x=360

x=360-165

so your third exterior angle is x=195 degree
