Whenever you multiply by a negative number.
Hopefully that helps you a little.
Answer:
45 or positive 45
Step-by-step explanation:
m(slope)= change in y/change in x
m=-17-(-5)/3-1
m=17+5/2
m=22/2
m=11
Answer:
100
Step-by-step explanation:
Solve for m
2m= 40
Divide both sides 2
m= 20
5(20)= 100
The interior angle of a regular octagon is 135 degrees.
<h3>What is an octagon?</h3>
An octagon is a polygon that has 8 sides. Therefore, a regular octagon is a octagon with all it sides and angles equal to each other.
Therefore, the sum of angles in an octagon is each interior angle multiply by the number of sides.
Therefore,
n = number of sides = 8
Hence,
interior angle = (n - 2)180 / n
interior angle = (8 - 2)180 / 8
interior angle = 6 × 180 / 8
interior angle = 1080 / 8 = 135°
