You asked:

Solve the equation \(90^{\circ} + 3 x + x = 180^{\circ}\) for the variable \(x\).

MathBot Answer:

The solution is: \[x = \frac{45 ^\circ}{2} \approx 22.5 ^\circ\]

\[\begin{aligned}90^{\circ} + 3 x + x &= 180^{\circ}\\4 x + 90 ^\circ &= 180 \text{deg}\\4 x &= 90 ^\circ\\x &= \frac{45 ^\circ}{2}\end{aligned}\]
