In regular polygons, if the number of sides, n, is odd, the lines of symmetry will pass through a vertex and the half of the opposite side.
Step-by-step explanation:
This is equivalent to say that a perpendicular bisector of a side of the regular polygon bisects the angle of the opposite vertex to the side, and divide the polygon into two symmetrical parts.
Answer:
option 4
Step-by-step explanation:
Answer:
y=40-15x
Step-by-step explanation:
Let x represent the number of hours.
We have been given that Dudley travels 30 miles every 2 hours, so distance covered in each hour by Dudley would be:
.
Since Dudley travels 15 km per hour, so distance covered in x hours would be 15x.
We have been given that Dudley wants to cover 40 miles. So we can represent our given information in an equation as:
, where, y represents number of miles he has left to travel, after biking x hours.
Answer:
The Second one
Step-by-step explanation:
In the picture above.
I hope that it's a clear solution.
Answer: n=15
Step-by-step explanation:
To find the perimeter, you add all of the side lengths together. This would make the equation 28+28+n+n. You already know the perimeter and are trying to find n. Your new equation is 28+28+n+n=86
You would then combine the like terms and get
56+2n=86
Then you would subtract 56 from both sides and get
2n=30
Finally, you want to divide both sides by 2 in order to get n alone. 30/2 is 15. Therefore,
N=15
