Equilateral triangle will always have a perpendicular bisector that is also an angle bisector.

Step-by-step explanation:

Equilateral triangle property:

  • All sides of the equilateral triangle are equal.
  • Angle of every equilateral triangle are equal to 60°.
  • Every altitude of an equilateral triangle is also a median and a bisector.
  • Each median is also an altitude and a bisector.
  • Each bisector is also an altitude and a median.

Therefore, by equilateral triangle property;

What is the distance between the points (-4,-8) and (10,-8)?
ioda

Answer: 14

Step-by-step explanation:

Input Data :

Point 1  ( x A , y A )  = (-4, -8)

Point 2  ( x B , y B )  = (10, -8)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points =  √ (x B − x A ) 2 + ( y B − y A ) 2

Solution :

Distance between two points =  √ ( 10 −  − 4 ) 2 + ( − 8 −  − 8 ) 2

=  √ 14 ^2 + 0 ^2

=  √ 196 + 0

=  √ 196 = 14

Distance between points (-4, -8) and (10, -8) is 14

Find the value of the combination. 10C0
Andrej [43]

Answer:The formula for a combination of choosing r unique ways from n possibilities is:

nCr  =   n!

  r!(n - r)!

where n is the number of items and r is the unique arrangements.

Plugging in our numbers of n = 10 and r = 0, we get

10C0  =   10!

  0!(10 - 0)!

10C0  =   3,628,800

  3,628,800
