Question

Determine the value of y.Question options:1) 46°2) 226°3) 132°4) 452°

Answer 1

Let us consider two tangents AB and BC with centre at O.

We know that angle AOC and angle ABC are supplementary.

Now,

`\begin{gathered} \angle AOC=360-226 \\ =134^o \end{gathered}`

Now,

`\begin{gathered} \angle AOC+\angle ABC=180 \\ 134+y=180 \\ y=46 \end{gathered}`

Hence, the correct option is (A)
