A is a binomial since it has only 2 values
Any triangle where the sum of the angles is over or under 180 cannot exist.
A 45-55-80 triangle can exist, but a 45-55-90 triangle cannot.
A 30-45-105 triangle can exist, but a 80-90-105 triangle cannot.
I'm not completely sure about what you are asking, but if its what i'm taking from this, tan A = 7/9 is finding the measure of angle A.
