Question

in the figure EF is parallel to CD and angle BCE = 20 prove that ab is parallel to CD

Answer 1

Answer:

angleAGH=100°

Step-by-step explanation:

AB||CD

So, angleAEG=angleDHF [Corresponding angles]

therefore, angleAEG=35°

angleAGH = angleBAC + angle AEG [By exterior angle theorem]

So,

angleAGH = 65°+35°

Hence,

angleAGH = 100°
