Step-by-step explanation:
given : two angles A1 = A2 = 60°
and A3 = 2A4
according to question :
A1 + A2 + A3 + A4 = 360°
60 + 60 + 2A4 + A4 = 360°
120 + 3A4 = 360°
3A4 = 240°
A4 = 80°
Now A3 = 2A4 => A3 = 160°
60 = 60 < 80 < 160 =>> A1 = A2 < A3 < A4
thus angle with 160° angle measurement is the greatest.

Answer:
A1 + A2 + A3 + A4 = 360°
60 + 60 + 2A4 + A4 = 360°
120 + 3A4 = 360°
3A4 = 240°
A4 = 80°
Now A3 = 2A4 => A3 = 160°
60 = 60 < 80 < 160 =>> A1 = A2 < A3 < A4
Thus angle with 160° angle measurement is the greatest.
