Find the measure of the unknown angle.59.5°146.9°?55.2°

The sum of the angles in a quadrilateral (a shape with four sides) is 360 degrees.

To find the unknown angle, you can subtract the sum of the known angles from 360.

Step 1: Add the known angles together. 59.5° + 146.9° + 55.2° = 261.6°

Step 2: Subtract the sum of the known angles from 360°. 360° - 261.6° = 98.4°

So, the measure of the unknown angle is 98.4°.
