1. **State the problem:** We are given a circle with a tangent line touching it at one point. The angle between the tangent line and the radius to the point of tangency is $x^\circ$. Another interior angle near the tangent point is $125^\circ$, and an exterior angle outside the tangent line is $22^\circ$. We need to write an equation to solve for $x$ and then find its value.
2. **Recall the tangent-secant angle theorem:** The angle between a tangent and a chord through the point of contact is equal to half the measure of the intercepted arc. Here, the angle $22^\circ$ is equal to half the difference between $125^\circ$ and $x^\circ$.
3. **Write the equation:**
$$22 = \frac{1}{2} (125 - x)$$
4. **Solve for $x$:**
Multiply both sides by 2:
$$2 \times 22 = 2 \times \frac{1}{2} (125 - x)$$
$$44 = \cancel{2} \times \frac{1}{\cancel{2}} (125 - x)$$
$$44 = 125 - x$$
5. **Isolate $x$:**
$$44 - 125 = 125 - x - 125$$
$$-81 = -x$$
6. **Multiply both sides by $-1$ to solve for $x$:**
$$-1 \times (-81) = -1 \times (-x)$$
$$81 = x$$
**Final answer:**
$$x = 81^\circ$$
