Answer:
The height of the equilateral triangle is 
Step-by-step explanation:
we know that
An equilateral triangle has three congruent sides, and three congruent angles that each measure 60 degrees
To find out the height of an equilateral triangle, apply the Pythagoras Theorem in the right triangle ABD
Remember that the height of an equilateral triangle bisects the base.
see the attached figure to better understand the problem

substitute the given values

The distance between the points is 
Step-by-step explanation:
The formula of the distance between two points
and
is 
To find the distance between two point:
- Put one of the two point as
- Put the other point as
- Substitute then in the rule of the distance and calculate the distance
∵ The two points are (18 , -2) and (6 , -10)
- Put (18 , -2) as
and (6 , -10) as
∴
= 18 and
= 6
∴
= -2 and
= -10
- Substitute them in the rule below
∵ 
∴ 
∴ 
∴ 
∵ (-12)² = 144 and (-8)² = 64
∴ 
∴ 
∵ 
∴ 
The distance between the points is
