Solution:

Note that:

AB = EF
BC = EG = 6x - 8
7x - 19 = 2x + 11
Perimeter of triangle: 24 + 2x + 11 + 6x - 8

Solving for x:

7x - 19 = 2x + 11
=> 7x - 2x = 19 + 11
=> 5x = 30
=> x = 30/5 = 6

Substitute the value of x into the expression (24 + 2x + 11 + 6x - 8):

24 + 2x + 11 + 6x - 8
=> 24 + 2(6) + 11 + 6(6) - 8
=> 24 + 12 + 11 + 36 - 8
=> 24 + 12 + 3 + 36
=> 75 units

The perimeter of the triangle ABC is 75 units.

(fx+cd)/(x-f)=1/2 solve for x

sesenic [268]

Answer:

Step-by-step explanation:

(fx+cd)/(x-f)=1/2

Cross multiplication,

2*(fx + cd) = 1 * (x-f)

2fx + 2cd = x - f

2fx - x = -2cd - f

x (2f - 1) = -2cd -f

x = (-2cd-f )/ (2f-1)
