Answer: 26

Explanation:

Two Angles are Complementary when they add up to 90 degrees (a Right Angle). Then

Answer:

The measure of
\angle A:


\angle A = 26\textdegree

Explanation:

Since both
\angle A and
\angle B are complementary (Which they both add up to 90°), and you want to find the measure of

Measure of
\angle A: unknown

Measure of
\angle B: 64°

Finding the measure of
\angle A:


90 - 64 = 26


\angle A = 26\textdegree

So, the measure for
\angle A is
26\textdegree.
