The problem asks to find the complement of an angle measuring 89°.

To find the complement of an angle, we use the formula:

$\text{Complement} = 90^\circ - \text{Given angle}$

Substituting the given angle:

$\text{Complement} = 90^\circ - 89^\circ = 1^\circ$

So, the complement of the 89° angle is 1°.

Would you like further details or have any questions? Here are some related questions:

1. What is the definition of complementary angles?
2. Can two angles have a sum greater than 90° and still be complementary?
3. What happens if the given angle is exactly 90°? Can it have a complement?
4. What is the difference between complementary and supplementary angles?
5. Can you find the complement of an angle greater than 90°?

Tip: Always remember, complementary angles add up to exactly 90°, while supplementary angles add up to 180°.
