Classify triangle abc by its angles if m

It seems that you missed the essential details for this question, but anyway, I have found the complete question. So given that angles m<A=32 and m<B=55, let us find first for the measure of angle c. So m<C= 180 - 32-55 = 93, so it is 93. Based on these measurements, Triangle ABC is an obtuse triangle. By definition, an obtuse triangle is a triangle in which one of its angles is obtuse or which measures more than 90 degrees. Hope this answer helps.

Because a perimeter is 2l + 2w, the formula is this:
2l + 6 = 24
2l = 18
l = 9
So the length is 9
