Hello!
The total number of degrees that a polygon must add up to are 360°.
We currently know that three of the angles are: 114°, 84°, and 94°.
We will now add up the total number of these three angles:
114+84+94= 292
To find the measurement of the last angle, we must subtract 292° from the total (360°).
360-292= 68°
The measurement of the unknown angle is 68°.
I hope this helps you!!
