Answer:
13.6 units (to 3 significant figures)
Step-by-step explanation:
C ( -4,6) and D (-4,-5)
the formula for distance is : √(x2 - x1)² + (y2-y1)²
in this case x1= -4 , x2= -4 and y1 =6 , y2 = -5
so substitute the values and you will get the answers

Answer:
360 degree
Step-by-step explanation:
The sum of all the exterior angles is 360 for any polygon.
This can be proved for polygon with 20 sides also.
We know that sum of all the angles of polygon is given by formula = (2*n -4) *90
where n is the no. of sides of polygon
for 20 sides polygon sum of sum of all the angles = (2*20 -4) * 90
= (40-4)*90 = 36*90 = 3240 degree
measure of each angle of polygon = sum of total angles of polygon/ no of sides of polygon = 3240/20 = 162
We also know that sum of interior and exterior angle of triangle is 180 degree, as interior and exterior angle lies on straight line and they are supplementary
so
162 + value of exterior angle = 180
=> value of exterior angle = 180 - 162 = 18
Value of one exterior angle is 18 degree
in 20 sided polygon there are 20 exterior angle
therefore, value of 20 exterior angle is 18*20 degree which is 360 degree.
__________________________________________________________
As a general point one can memorize than sum of all the exterior angle for a polygon with any number of side is 360.
