Question 1014816: Jeanie joined together a right angle (90°) and unknown angle for her paiting to create an angle 389°.what is the measure of the unknown angle?
We use N° for the measure of the unknown angle. Then:
90° + N° = 389°
Subtract 90° from both sides so as to leave only the N°.
90° + N° - 90° = 389° - 90°
N° = 299°
Now the unknown angle is not unknown anymore. It's now KNOWN! :)
