Let the unknown angle be x.

The sum of unknown angle and angle 56 degree is equal to 90 degree. So equation is,


x+56=90

Simplify the equation to obtain the value of unknown angle, x.


\begin{gathered} x+56=90 \\ x=90-56 \\ =34 \end{gathered}

So equation for unknown angle x, is x + 56 = 90 and measure of unknown angle is 34 degree.
