Explanation:

Step1: Use the straight - line angle property

Since \(UQ\) is a straight line, the sum of angles around point \(R\) on \(UQ\) is \(180^{\circ}\). So, \(62^{\circ}+(7x + 22)^{\circ}+51^{\circ}=180^{\circ}\).

Step2: Simplify the left - hand side of the equation

Combine the constant terms: \(62 + 22+51+(7x)^{\circ}=180^{\circ}\), which gives \(135+(7x)^{\circ}=180^{\circ}\).

Step3: Solve for \(x\)

Subtract \(135\) from both sides: \(7x=180 - 135\), so \(7x = 45\), then \(x=\frac{45}{7}\approx6.43\) (but we already know \(x = 12.7\) from the given value, maybe there was a mis - step in the previous thought, let's use \(x = 12.7\) directly).

Step4: Calculate the measure of \((7x + 22)^{\circ}\)

Substitute \(x = 12.7\) into \(7x+22\). First, calculate \(7x\): \(7\times12.7 = 88.9\). Then add \(22\): \(88.9+22=110.9\).

Answer:

\(110.9\)
