Heyya

We know that the sum of all the angles of a quadrilateral is 360

So, first angle= 120° [given]

Second angle= 80 [given]

Third angle=Fourth angle [given]

Let the third and fourth angle be x, so

120°+80°+x+x=360°

200°+2x=360°

2x=360-200

x=160/2

x=80°

Hence, the third and the fourth angles are 80° each

Hope I've solved your question...
