Answer 3

easy 1minute I am answering u now

Answer 4

Angle CDX = 56, so, 1/2 angle CDX = angle XDB = 28 dehrees

Answer 5

okay thanks :)

Answer 6

they never say CDX = XDB

Answer 7

so you have to prove by complimentary angles

Answer 8

because it is a parellelogram we can prove right?

Answer 9

i used equal angles to prove it

Answer 10

show me ur method?

Answer 11

Given, CD is parallel to EB, so angle CDX = angle EDX = 56 degrees. So, angle DXB = 180 - 56 = 124 degrees

Answer 12

So, angle XBD = 180 - (124+28) = 28 degrees = angle BDX
Hence, traingle BDX is isosceles

Answer 13

EB // DC => BDC = EBD
EBD = EAD => EA // BD => AEB = ADB
=> EBD = EBD => BDX isosceles

Answer 14

thanks once again guyz :D

Answer 15

no pb
