Rr = 51 : 68
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
5/6 =0.8333
12x0.8333 = 10
An obtuse angle is an angle that is in between 90 degrees and 180 degrees. It looks like this
interior angle of a regular 18-gon.
It is easier to calculate the exterior angle of a regular polygon of n-sides (n-gon) by the relation
exterior angle = 360/n
For a 18-gon, n=18, so exterior angle = 360/18=20 °
The value of each interior angle is therefore the supplement, or
Interior angle = 180-20=160 degrees.
Naming of a 9-gon
A polygon with 9 vertices is called a nonagon (in English) or enneagon (French ennéagone, but the English version is sometimes used)
You had a good start with the correct answer.
Exterior angle of a 15-gon
The exterior angle of a 15-gon can be calculated using the relation given in the first paragraph, namely
Exterior angle = 360/15=24 degrees
To find how many miles he went in 1 hour, divide 62.3 by 3.5.
62.3 / 3.5 = 17.8
