Answer:
The interior angles are:
180-30=150 degrees
180-60=120 degrees
180-90=90 degrees
Step-by-step explanation:
Exterior angle sum property of a polygon: 360 degrees
:. , x+x+2x+2x+3x+3x=360
=> 12x=360
=>x=30
The exterior angles are 30,30,60,60,90,90.
:. The interior angles are:
180-30=150
180-60=120
180-90=90
When you add them, you get:
150(2)+120(2)+90(2)= 300+240+180= 720
