In the figure given alongside, `AB||CD,EF||BC,angleBAC=60^(@)andangleDHF=50^(@)."Find "angleGCHandangleAGH`.

Text Solution

Verified by Experts

The correct Answer is:
`angleGCH=60^(@),angleAGH=110^(@)`
`angleACD=angleBAC=60^(@)" "["alternate int."angles]`
In `DeltaGCH` we have `60^(@)+50^(@)+angleHGC=180^(@)`.
`:.angleHGC=70^(@)andangleAGH=(180^(@)-70^(@))=110^(@)`.
