Can i know how the right answer is B?

Look at the attached sketch..
In ∆BCD, BD=DC, so an isosceles triangle..y=180-(2*65)=180-130=50
In ∆ABD, AB=BD, so aga8n an isosceles triangle..
Angle ABD=180-65=115.. so x+x+115=180...x=32.5

So y>x or B>A

B

A) Quantity A is greater.

D) The relationship cannot be determined from the information given.

In the $\triangle BDC$

$BD = DC$, so it is an isosceles $\triangle$

i.e. $\angle DBC = \angle DCB = 65°$

and $\angle y$= $180° - (2 * 65°) = 50°$

Now in $\triangle ADB$

$\angle DAB = \angle BDC = x°$ ( since AB = BD)

therefore $\angle DBC = \angle DAB + \angle BDC$ (exterior angle is sum of two opposite interior angle)

or$65° = 2x°$

or $x° = 32.5°$

therefore QTY A < QTY B

In the $\triangle BDC$

$BD = DC$, so it is an isosceles $\triangle$

i.e. $\angle DBC = \angle DCB = 65°$

How do we know that ∠DBC should equal ∠DCB?

and $\angle y$= $180° - (2 * 65°) = 50°$

Now in $\triangle ADB$

$\angle DAB = \angle BDC = x°$ ( since AB = BD)

therefore $\angle DBC = \angle DAB + \angle BDC$ (exterior angle is sum of two opposite interior angle)

or$65° = 2x°$

or $x° = 32.5°$

therefore QTY A < QTY B
