A decagon has 10 sides. If the polygon is symmetrical, the angle of rotation is given by the following equation:
360 / (number of sides)
Therefore,
360 = 10 = 36.
The interior angles are determined by the following equation:
180 - (angle of rotation)
Therefore,
180 - 36 = 144
The answer is A.
Answer:
Step-by-step explanation:
The midpoint between two points is the average of the coordinates.
mp=((x2+x1)/2, (y2+y1)/2)
In this case we are given one end point and the midpoint.
Just look at the x coordinate first.
If the mid x is 8 and the x from j is 10 we have
(10+x)/2=8
10+x=16
x=6, now for the y for j when y=6 and mid y of 5
(6+y)/2=5
6+y=10
y=4
So the coordinates of K are (6,4)
Answer:
$37.5
Step-by-step explanation:
If you're earning $150.00 per week and if you save 25% then
you're saving 25% of $150.00 weekly.
To find this amount we can multiply 0.25 with 150.00=37.5.
