Given a cyclic quadrilateral

The sum of the opposite angles = 180

so,


\begin{gathered} 2y+90=180 \\ (5x-1)+76=180 \end{gathered}

solve the first equation to find y as follows:


\begin{gathered} 2y=180-90 \\ 2y=90 \\ y=(90)/(2)=45 \end{gathered}

Solve the second equation to find x as follows:


\begin{gathered} 5x-1+76=180 \\ 5x+75=180 \\ 5x=180-75 \\ 5x=105 \\ x=(105)/(5)=21 \end{gathered}

so, the answer will be:

x = 21

y = 45
