In the given figure, chords AD and BC in the circle, are extended to E and F, respectively.
If ∠CDE = 85o; ∠DCF = 94o, then the value of ∠EAB is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e 179o.
| Understanding/Application |

From the figure- ∠CDE + ∠CDA = 1800 (Linear pair) ∠CDA = 180 - 85 ∠CDA = 950 ∠DCF + ∠DCB = 1800 (Linear pair) ∠DCB = 180 - 94 ∠DCB = 860 |

In the quad. ABCD - ∠ABF + ∠DCB + ∠CDA + ∠EAB = 3600 ∠ABF + ∠EAB = 360 - 86 - 95 ∠ABF + ∠EAB = 1790 |
