Asap i’m doing it in class rn for extra credit

Step-by-step explanation:

An angle is formed by three vertices.

Starting with as fixed vertices and changing the vertex gives us angle of the first line mentioned there.

Starting with as fixed vertices and changing the vertex gives us angle of the second line mentioned there.

Starting with as fixed vertices and changing the vertex gives us angle of the third line mentioned there.

Starting with as fixed vertices and changing the vertex gives us angle of the fourth line mentioned there.

Starting with as fixed vertices and changing the vertex gives us angle of the fifth line mentioned there.

Starting with as fixed vertices and changing the vertex gives us angle of the last line mentioned there.

Thus those are the maximum possible angles.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
