Supplementary angles are two angles whose measures add up to 180 degrees.

Given that angle A is 43º, to find the measure of angle CBD, you can use the formula for supplementary angles:

\[
\text{Measure of angle CBD} = 180º - \text{Measure of angle A}
\]

Substituting the given value:

\[
\text{Measure of angle CBD} = 180º - 43º = 137º
\]

Therefore, the measure of angle CBD is 137º.
