Number of angles = number of sides

180 - 120 = 60 (calculating the exterior angle)

360 / 60 = 6

There are 6 sides.

Hope this helps! :)

Formula for internal angles of a n gon is (n-2)180/n

so it has 120 on each of the angles

120=(n-2)180/n
times both sides by n
120n=180n-360
minus 180n both sides
-60n=-360
divide both sides by -60
n=6

6 sides

What are the coordinates of the vertex of y = x2 – 2x – 7?
Elza [17]
Rearrange  to vertex form:-

y = x^2 - 2x - 7
y = (x - 1)^2 - 1 - 7
y = (x - 1)^2 - 8

The vertex is at the coordinates (1, -8)
