1. **Stating the problem:** We need to find the values of angles $h$ and $j$ formed by two intersecting chords inside a circle, given one angle is $39^\circ$ and the other angles are related.
2. **Relevant formula:** When two chords intersect inside a circle, the measure of each angle formed is half the sum of the measures of the intercepted arcs.
3. **Important rule:** Vertical angles formed by intersecting chords are equal.
4. **Step 1:** Since the angle adjacent to $h$ is $39^\circ$, and $h$ is its vertical angle, we have:
$$h = 39^\circ$$
5. **Step 2:** Angles $h$ and $j$ form a linear pair, so they are supplementary:
$$h + j = 180^\circ$$
6. **Step 3:** Substitute $h = 39^\circ$ into the equation:
$$39^\circ + j = 180^\circ$$
7. **Step 4:** Solve for $j$:
$$j = 180^\circ - 39^\circ = 141^\circ$$
**Final answers:**
$$h = 39^\circ$$
$$j = 141^\circ$$
