Question

Give that AB||CD , find the unknown value of in the following figure

Answer 1

Answer:

draw EF line parallel to AB and CD.

therefore, BAE+FEA=180 (CORRESPONDING ANGLES)

and, FEC+DCE=180 (CORRESPONDING ANGLES)

56°+ AEF= 180

AEF=180-56°

=124°

CEF=180-41°

=139°

Therefore, x= 124°+139°

=263°
