1. Two angles are complementary if their measures add up to $$90^\circ$$.

2. Let $$x$$ be the measure of the complementary angle. Then, we have:
   $$
   18.4^\circ + x = 90^\circ
   $$

3. To solve for $$x$$, subtract $$18.4^\circ$$ from both sides:
   $$
   x = 90^\circ - 18.4^\circ
   $$

4. Calculate the difference:
   $$
   x = 71.6^\circ
   $$

Thus, the measure of the complementary angle is $$71.6^\circ$$.
The complementary angle is $$71.6^\circ$$.
