These two angles are complementary.

Question

1. X and 2. 45°
What is the measure of /_x?
x = [?]°

Answer 1

Complementary angles are two angles whose measures add up to 90 degrees. Given that one angle is 45°, we can set up the equation:

\( x + 45° = 90° \)

To find the measure of angle \( x \), subtract 45° from both sides:

\( x = 90° - 45° \)

Therefore,

\( x = 45° \)

So, the measure of angle \( x \) is 45°.
