GEOMETRY: PLEASE HELP!!
Aloiza [94]

Answer:

GF=72

Step-by-step explanation:

All triangles in the given figure are similar, from SAS. Notice that marked in the diagram, CD=DE=EF=FA.

For triangle \triangle CGF was base GF, leg CF contains three of these marked segments. In triangle \triangle CHE with base HE, leg CE has two of these marked segments. By definition, similar polygons have corresponding sides in a constant proportion. Therefore, the length of GF must be 3/2 the length of EH. Since the length of EH is given as 48, we have:

GF=\frac{3}{2}EH, \\\\GF=\frac{3}{2}\cdot 48,\\\\GF=\boxed{72}

Find the solution to the system of equations.<br> 1 + 3y = 4<br> 2r + 5y = 12
ivann1987 [24]

Answer: {x,y}={-1,2}

step-by-step explanation:

// Solve equation [2] for the variable  x

 [2]    2x = 5y - 12

 [2]    x = 5y/2 - 6

// Plug this in for variable  x  in equation [1]

  [1]    2•(5y/2-6) + 3y = 4

  [1]    8y = 16

// Solve equation [1] for the variable  y

  [1]    8y = 16

  [1]    y = 2

// By now we know this much :

   x = 5y/2-6

   y = 2

// Use the  y  value to solve for  x

   x = (5/2)(2)-6 = -1

Solution :

{x,y} = {-1,2}
