the three angles are 60,80,120
suppose 4th as x
sum of 4 angles = 360
60+80+120+x=360
260+x= 360
x=360-260
x=100
so, 4th angle =100
hope it hlps u

Hey there!
By angle sum property of a Quadrilateral:
∠A + ∠B + ∠C + ∠D = 360°
60° + 80° + 120° + ∠D = 360°
∠D = 360° - 260°
= 100°
Hence,
The angle of Fourth vertex is = 100°
Cheers!
