So, the triangle is equilateral, all its sides are equal⇒
AB=BC=AC=8
In an equilateral triangle, the height is also the median, so it divides the sides into 2 equal parts⇒
AO=OC=8:2=4
by the Pythagorean theorem

Answer: BO=4√3

Answer:
y = 4.375x + 2.5
Step-by-step explanation:
The equation of the line is expressed as y = mx+c
m is the slope
c is the intercept
Using the coordinate points (0, 2.5), (4, 20)
Slope m = 20-2.5/4-0
m = 17.5/4
m = 4.375
Get the intercept
Substitute (0, 2.5) and m = 4.375 into y - mx+c
2.5 = 4.375(0) + c
2.5 = c
Get the equation required
y = 4.375x + 2.5
Answer:
C. c = 10
Step-by-step explanation:
You have to use the Pythagorean theorem:
c² = 6² + 8²
c² = 36 + 64
c² = 100
c = √100
c = 10
Answer:
C
