Answer 1

Check the picture below.

Answer 2

Option A. will be the answer.

Explanation:

It is given in the diagram attached, AB and BC are the tangents to circle O.

We have to find the measure of ∠ABC.

By the theorem,

Measure of ∠ABC which inscribed within the tangents will be
`=(1)/(2)(arcADC-arcAC)`

`=(1)/(2)(226-134)`

`=(1)/(2)(92)`

= 46°

Option A. will be the answer.
