A side of the triangle below has been extended to form an exterior angle of 129°. Find the value of x x. 20° 129° x°

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.

C, e, and a (hope it )
