Find the measure of the third angle of a triangle if the measures of the other two angles are given. 102.9 and 40.4

Aye bruh i don’t know this but someone else who smarter than us will answer this

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
