The angle measurements in the diagram are represented by the following expressions.
$\qquad \begin{eqnarray} \blueD{\angle A} &=& \blueD{6x + 5^\circ} \\ \green{\angle B} &=& \green{4x + 45^\circ} \end{eqnarray} $

**Solve for $x$ and then find the measure of $\blueD{\angle A}$:**
$\blueD{\angle A} = $ [[☃ math-keypad 2]] $^\circ$
