Answer:
Step-by-step explanation:
Area = 1/2 (a * p)
585 = 1/2 (13 * p)
1170 = 13 * p
13*p = 1170
p = 1170/13
p = 90
There are six sides to a regular hexagon. Therefore divide the perimeter by 6.
side = p / 6
side = 90 / 6
side = 15
Angle between two vectors = arc cos [(u.v)/(abs(u) x abs (v))]
u.v = (10 x 9) + (6 x 5) = 90 + 30 = 120
abs (u) =

abs (v) =

Angle between the two vectors = arc cos [120 / (11.66 x 10.30)] = arc cos [120 / 120.1] = arc cos [1] = 0
Since the angle between the two vectors is 0,
therefore, the angles are parallel

Step-by-step explanation:
For a function, each x value has only one y value. 2, 3, and 4 are already used up.

When you multiply the sides my a constant, the area multiplies by the constant squared.
ex. sides multiplied by 3, area multiplied by 9.
