Answer: The value of CD is 16 units.
Step-by-step explanation:
Since we have given that
AB = 12 cm
MN = 14 cm, where, M and N are the midpoints of AD and BC respectively.
We need to find the value of CD.
As we know that
Hence, the value of CD is 16 units.

∠LEB =35°
∠LEF =35° as EL is the bisector of ∠FEB
∠FEB = 70°
As AB || CD
∠FEB = ∠EFC (Alternate interior angles)
∠EFC = 70°
Also ∠EFC + ∠CFQ = 180° ( Linear pair)
70° +∠CFQ = 180°
∠CFQ = 180 -70
∠CFQ = 110°

ABCD is a parallelogram, diagonals AC and BD intersect at O
In triangles AOD and COB,
∠DAO = ∠BCO (alternate interior angles)
AD = CB
∠ADO = ∠CBO (alternate interior angles)
AOD COB (ASA)
Hence, AO = CO and OD = OB (c.p.c.t)
Thus, the diagonals of a parallelogram bisect each other.

3√12 ÷ 6√27
= 3√4 × 3 ÷ 6√9 × 3
= 3 × 2√3 ÷6 ×3 √3
= 6√3 ÷ 18√3
= 6/18
= 1/3 is not a surd
