Step 1: Recall the definition of complementary angles
Two angles are complementary if their sum is 90°. Let the angle be xxx. Then its complement is 90−x90 - x90−x.
Step 2: Set up the equation
If the angle is equal to its complement:
x = 90 - x
Step 3: Solve for x
x + x = 90
2x = 90
x = 45
Step 4: Verify
Complement of 45° = 90 - 45 = 45°
