In the given figure, angleOAB=110^@ and ...

In the given figure, `angleOAB=110^@` and `angleBCD=130^(@)` then `angleABC` is equal to

A

`40^(@)`

B

`50^(@)`

C

`60^(@)`

D

`70^(@)`

Text Solution

Verified by Experts

The correct Answer is:
C
`angleABE+angleOAB=180^(@)`
`implies angleABE+110^(@)=180^(@)implies angleABE=70^(@)`.
And, `angleBCD+angleCBF=180^(@)`
`implies 130^(@)+angleCBF=180^(@) implies angleCBF=50^(@)`.
`:. 70^(@)+x^(@)+50^(@)=180 implies x=60^(@)`.
