Answer:
The angle will be 130 degrees
Step-by-step explanation:
50 at the center translates to 50 at the outer rim.
this means it will be 310-50 divided by 2
260 divided by 2 equals 130
2x + 30 = -20x + 8
2x + 20x = 8 - 30
22x = -22
x = 1
A 4-sided thing with area of 30 and perimeter of 34
has these dimensions:
<em> Length = 15</em>
<em> Width = 2</em>
That's no square.
