It seems like you're asking for the measure of the third angle in a triangle. The sum of all angles in a triangle is always 180 degrees.

Here's how you can find it:

Step 1: Add the measures of the two given angles: 98.9° + 163.9° = 262.8°

Step 2: Subtract this sum from 180° to find the measure of the unknown angle: 180° - 262.8° = -82.8°

However, the measure of an angle in a triangle cannot be negative. This means that the given angles do not form a triangle. Please check the values of the angles again.
