Find all outer angles of a quadrilateral shown in the picture.
1st Angle :- 130°
2nd Angle :- 76°
3rd Angle :- 60°
4nd Angle :- x° = 94°
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.
130° + 76° + 60 = 266°
Step 2: Subtract the sum from 360° to determine what remains for the fourth angle.
360° - 266° = 94°
The measure of the unknown angle is 94°
