Dear student

In △ ABC, ∠ A = 45 ° and ∠ B = 65 ° We know that ∠ A + ∠ B + ∠ C = 180 ° [Angle sum property] \Rightarrow ∠ C = 180 ° - 45 ° - 65 ° \Rightarrow ∠ C = 70 ° Now, In △ ABC ∠ B > ∠ A [Given] Then AC > BC [The side opposite to the larger angle is larger] \Rightarrow BC < AC . . (1) Also, ∠ C > ∠ B Then, AB > AC [The side opposite to the larger angle is larger] \Rightarrow AC < AB . . . (2) From (1) and (2), we get BC < AC < AB
