Answer 1

Answer:

therefore, side AB is the longest side in the triangle ABC.

Because side opposite to the greatest angle in the triangle is the longest.

Answer 2

Answer:

120+Angle ABC =180[Linear pair]

Angle ABC =180-120

Angle ABC=60

100+Angle ACB=180[Linear pair]

Angle ACB=180-100

Angle ACB =80

Angle ACB =AB=80[Side opposite to larger angle is longest]

Therefore, AB is longest
