Question

Triangle ABC with sides labeled as a, b, and c. Angle A measures 80 degrees. Angle B measures 31 degrees. Angle C measures 69 degrees.

What is the order of the side lengths of triangle ABC from largest to smallest?

c, b, a

b, a, c

c, a, b

b, c, a

Answer 1

the length of each side corresponds to its opposite angle

angle A is the biggest angle (because 80 is the biggest of the 3 numbers)
that means the side opposite A is the longest side
