[tex]\angle BAM=4x+22[/tex]
Right angle means that the angle is equal to 90 degrees
We will thus proceed by equating BAM = 90 degrees, we have:
[tex]\begin{gathered} 4x+22=90 \\ \text{Subtract 22 from both sides, we have:} \\ 4x+22-22=90-22 \\ 4x=68 \\ \text{divide through both sides by 4, we have:} \\ \frac{4x}{4}=\frac{68}{4} \\ x=17^{\circ} \end{gathered}[/tex]
x = 17
