Octagon:
= [(8-2)×180]÷8
= 135
Angle of LMN is:
= 360-135-60
= 165
Angle of EMN is:
= 180÷3
= 60
The number of side is :
[(n-2)×180]÷n = 165
(180n-360)÷n = 165
180n-360 = 165n
180n-165n = 360
15n = 360
n = 360÷15
n = 24
So, the number of side of the regular polygon R is 24.
Hi there!
To solve for x, we need to simplify:
9 - x/5 = 3
-x/5 = -6
x/5 = 6
x = 30
Hope this helps!
Answer:
-10
Step-by-step explanation:
Note that the points plotted on the line is by 2 (essentially, each line signifies 2).
The blue point is on the 5th line from the 0. 5 x -2 = -10
-10 is your answer.
