In the given figure, side BC of `DeltaABC` is produced to D. If `angleACD=128^(@)andangleABC=43^(@),"find "angleBACandangleACB`

Text Solution

Verified by Experts

The correct Answer is:
`angleBAC=85^(@),angleACB=52^(@)`
`angleBAC+angleABC=ext.angleACDimpliesangleBAC+43^(@)=128^(@)impliesBAC=85^(@)`
Also, `angleBAC+angleABC+angleACB=180^(@)."Find "angleACB`.
