Answer:
We have been given three angles and need to determine the measure of the fourth.
Step 1: Add together the measures of the known angles.
98° + 44° + 73° = 215°
Step 2: Subtract the sum from 360° to determine what remains for the fourth angle.
360° - 215° = 145°
The measure of the unknown angle is 145°.
