Question

Given that AB // CD, find the values of the unknowns
in each of the following figures.​

Answer 1

Answer:

see the attachment. below

Answer 2

Answer:

c=39°,d=77°,h=71°

Step-by-step explanation:

∠EHF is a liner pair,so

45°+h+64=180°

       h+109°=180

               h=180-109

               h=71°.    .....[1]

if AB is parallel to CD then,

   ∠h=∠GIC  ....[alternate interior angles are equal]

     71=32°+c  ......[from 1]

     71-32=c

      39°=c   ......[2]

we know that the sum of all angles of triangle sum up to 180°

therefore,

64°+d°+c°=180°

64°+d°+39°=180°   [from 2]

        d°+103°=180

                  d°=180-103

                    d°=77°
