Supplementary angles add up to \(180^\circ\). Given the measures of the angles \(m∠TUV = (2x - 25)^\circ\) and \(m∠VUW = 110^\circ\), we can set up the equation as follows:
\[ (2x - 25) + 110 = 180 \]
Now, simplifying the equation:
- Combine like terms: \[ 2x - 25 + 110 = 180 \implies 2x + 85 = 180 \]
So the equation to solve for \(x\) is:
\[ 2x + 85 = 180 \]
