Dude I don’t think using this for an exam is it but ok
Answer:
<ABC
Step-by-step explanation:
When you use three points, two points must be on the rays of the anlge. The middle point must be the vertex.
Answer: <ABC
All four angles are exterior angles of the quadrilateral.
We know that the sum of exterior angles of any polygon is 360 ° .
So we can add together the four angles and solve for x:
(x+16)+(3x-1)+6x+5x = 360
15x+15=360
15x=345
x=345/15=23 °
Answer:
The number of edges is 
Step-by-step explanation:
we know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
so

In this problem we have

substitute and solve for E


The inverse function theorem says

We have

defined on
, for which we get

and

The derivative of
is

So we end up with
