In the adjacent figure if CF||DE||AB and EF||BC then what's the measure of angle CFE |
|
Answer» Answer: as per the diagram,lines CD||EF and CE is transversal we know that SUM of interior angles is 180° angle ECD+angle CEF =180° angle ECD+130°=180° angle ECD =180°-130° angle ECD= 50° as per the diagram lines parallel to AB||CD and CA is transversal we know that alternate angles are equal angleBAC=angle ACD angle BAC=angle ACE+angle ECD 70°=angle ACE+50° 20°=angle ACE therefore angle ACE=20° I hope this helps you please mark me as branlist |
