Sin(65)=height/AD
AD= height/sin(65)
Also
BC= height/sin(62)
Since sin(65)>sin(62),
Length BC is greater and consequently, Quantity B is greater (option B)

There is nothing that observation to solve this question in 5 seconds

BC is the opposite side to 65 D angle

AD is opposite to angle C of 62 °

BC must be > than AC

But, A is 115° and B is 118°. BC is also opposite to A and AD is also opposite to B.
This way, AC > BC.
I don't understand which angle should I consider as opposite angle.

Generate a test case AD parallel to BC.
ADC = 90 degrees and BCD is 45 degrees.

Observe and you realize, small the angle greater the length
