Answer:
10
Explanation:
The sum of exterior angles for any polygon is 360.
so first add up all the given exterior angle:
30+35 = 65.
next, find all the exterior angles that you can find:
Exterior angle = 180-interior angle
so:
180-90 = 90
180-135 = 45
180-120 = 60
180-90=90
These are all that we can find.
now add these to 65:
90+45+60+90+65 = 350
To find x, subtract 350 from 360, which is the sum of exterior angles.
360-350 = 10
Hope this helps
Good Luck
