Given:

A cyclic quadrilateral and two opposite angles of it in the form of y.

To find:

The value of y.

Solution:

We know that, opposite angles of a cyclic quadrilateral are supplementary angles. So, their sum is
$180^\circ$ .

The measures of opposite angles of cyclic quadrilateral are y and 2y. So,

$y+2y=180^\circ$

$3y=180^\circ$

Divide both sides by 3.

$y=(180^\circ)/(3)$

$y=60^\circ$

Therefore, the value of y is
$60^\circ$ .
