In parallelogram ABCD , what is the measure of ∠ADC?

(1) The measure of ∠ABC is greater than 90/ Clearly insufficient.

(2) The measure of ∠BCD is 70. Usefull propery: the adjacent angles of a parallelogram are supplementary (supplementary angles are two angles that add up to 180°), so ∠BCD + ∠ADC = 180 --> 70 + ∠ADC =180 --> ∠ADC = 110. Sufficient.

Answer: B.

from, st(1) more thn one possibilities ...pls read properties of parallelogram...
from st(2) it is clear tht ∠BCD + ∠ADC = 180 , so we get ∠ADC
i think , from st(2) we can answer ths Qs!

(1) The measure of ∠ABC is greater than 90
(2) The measure of ∠BCD is 70

(1) This leads to several possible answers, hence insufficient.

(2) ∠BCD + ∠ADC = 180 As we already know that the first one is 70, the second is 180-70. Thus, sufficient.

In order to get clarity on such questions, we have a targeted quant course for candidates preparing for the GMAT. You can find more details here:
