Answer:
this question is weirdly worded. i think you meant to type "three angles of a hexagon....." I'll do my best.
Step-by-step explanation:
sum of angles in a polygon: (n-2) 180° where n=#of sides of the polygon
(6-2) 180°
(4) 180°
720°
1a + 1a + 1a + 0.5a + 0.5a + 0.5a = 720°
4.5a = 720°
a = 720°/4.5
a = 160
0.5a = 80
Check
3(160) + 3(80)
480 + 240 = 720
