Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form
d1i1m1o1n [39]

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The length of GF is 254 units.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

Since a centroid of a triangle divides the median into a ratio of 2:1. Therefore, the ratio of AG: DG is,

AG / DG = 2/1

(19x+14)/(9x+20) = 2/1

19x + 14 = 18x + 40

19x - 18x = 40 - 14

x = 26

Assuming the triangle is an equilateral triangle, therefore, the length of GF will be,

GF = DG = 9x+20

GF = DG = 9(26) + 20

GF = 254 units

Hence, the length of GF is 254 units.

Can someone please help me on this question? I am very confused!
n200080 [17]

Here we are give the value for π and Diameter of the circle fence

π=3.14

Diameter = 16

Radius = Diameter/2

2πr = 2(3.14)(8)

Circumference = 50.27

Now to fine the square fence length so we do 16*4 = 64

64-50.27 = 13.73 in

Therefore, the square fence is 13.73 inches longer than the circle fence

D=vt-(1/2)at^2 to find a. In the formula, d is displacement, v is final velocity, a is acceleration, and t is time
larisa86 [58]

Answer:

  a = 2(vt -d)/t^2

Step-by-step explanation:

Add the term containing "a":

  d + a(t^2/2) = vt

Subtract d:

  a(t^2/2) = vt -d

Multiply by the inverse of the coefficient of "a":

  a = 2(vt -d)/t^2
