Answer:
I’m pretty sure it 15cm
Step by step
We know that -1/4x means we have a negative slope, which excludes the 1st graph from our answer choices.
Second, we know that the y-intercept has to be 3, excluding the second and third graph.
This leaves us with the 4th graph as our answer
Answer:
°
Step-by-step explanation:
An alternative method is to use the exterior angle.
the sum of the exterior angles is ALWAYS 360 °
So you can find the size of the exterior angles of a regular polygon quite easily:
If there are 18 sides ( n = 18 ) , then each exterior angle is:
°
The sum of the exterior and interior angles is 180° because they are adjacent angles on a straight line.
∴ each interior angle is 180° - 20° = 160°
