Find the missing angle in a quadrilateral with angles measuring 45°, 75°, and 135°.

• 120°

• 60°

• 105°

• 90°

Answer explanation

To find the missing angle in a quadrilateral, subtract the sum of the given angles from 360°. 360° - (45° + 75° + 135°) = 105°. Therefore, the missing angle is 105°.
