Hii

Please observe that both statement 1 & 2 gives same results.

(1) Angle DAB = 45 degrees

if in quadrilateral, Angle DAB = 45 (St1), Angle ABC= 110 (Question stem)

then as the sum of Angles in a Quadrilateral is 360,

Angle ADC + angle BCD = 205 degrees= Statement 2.

(you need not calculate this, you can infer that Angle ADC + angle BCD = can be calculated from St 1)

(2) Angle ADC + angle BCD = 205 degrees

Since, both statement 1 & 2 gives same results Answer is D or E.

Eliminate all other choices.

We need to check any one of the statements, Let check using statement1

Now , we can solve this question using construction approach:

Try to construct the Quadrilateral.

See the Sketch.
