Answer:
Let x be the fourth angle.
100+68+82+x=360 (Angle sum property of quadrilateral)
200+x=360
x=360-200
x=160

Given : the three angles of a quadrilateral are 100°, 68°, 82°
To Find : The fourth angle
Solution:
Sum of all four angles of a Quadrilateral is 360°
There Given angle are :
100°, 68°, 82°
Assume that Fourth Angle is x°
Hence
100° + 68° + 82° + x° = 360°
=>250° + x° = 360°
=> x° = 360° - 250°
=> x° = 110°
The fourth angle is 110°
