Given data:

The given angle M is ∠M=(5x+10)°.

The given angle R is ∠R=55°.

The expression for the sum of both the angles is,


\angle M+\angle R=90^(\circ)

Substitute the given values in the above expression.


\begin{gathered} (5x+10)^(\circ)+55^(\circ)=90^(\circ) \\ 5x=25^(\circ) \\ x=5^(\circ) \end{gathered}

Thus, the value of x is 5 degrees.
