What is the value of x?

Answer is X = 82,
Triangle is obtuse which is 180 degree because when you add 45 and 53 together its 98, so just subtract 98 from 180, you’ll get 82!

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.
