Question

If each quadrilateral below is a square, find the missing measure

Answer 1

`x=11`

Step-by-step explanation

The figure given is a square.

Each angle in a square is 90 degrees and the diagonals bisect each angle.

This means that :

`\begin{gathered} 6x-21=45 \\ \text{Collect like terms:} \\ 6x=45+21 \\ 6x=66 \\ \text{Divide through by 6:} \\ x=(66)/(6) \\ x=11 \end{gathered}`

That is the value of x.
