Question

19.02 M)Which equation could be used to solve for the measure of angle O?(1 point)

Answer 1

Given the cyclic quadilateral below,

In a cyclic quadilateral, the sum of angles is 360°

The sum of the opposite angles of a cyclic quadilateral is 180° i.e,

`\begin{gathered} x^0_{_{_{_{}}}}+z^0=180^0_{_{}} \\ w^0+y^0=180^0 \\ (\text{Sum of the opposite angles of a cyclic quadilateral)} \end{gathered}`

Hence, the equation to find the measure of angle O i.e x° is,

`x^0_{_{_{_{}}}}+z^0=180^0_{_{}}`
