True False

∠5 = 28°
True – ∠5 = 28°
False – ∠5 = 28°
∠6 = 28°

Without the context in which angles 5 and 6 are described, it's impossible to determine the truth value of these statements. The truth or falsehood of statements about the measures of specific angles depend on the given geometric figures, postulates, theorems, or previously established measurements within a problem.

If you provide additional information about angle 5 or angle 6, such as their relationships within a particular geometric figure, then the truth of these statements can be determined. Otherwise, I cannot provide a conclusive answer to whether these statements are true or false.
