Answer:

  • x = 8 inches

Step-by-step explanation:

<u>As the triangles are similar, their corresponding sides will have same ratio:</u>

  • left short side /right short side = left long side / right long side

or simpler

  • s₁/s₂ = l₁/l₂

<u>Substitute values to find the missing one:</u>

  • 4/x = 10/20
  • 4/x = 1/2
  • x = 4*2
  • x = 8

The missing side is 8 inches long

Y-1=4y-2/3<br> y=_____<br> solve
Vikki [24]
Y - 1  =  4y - 2/3.      Move the ys over to one side,  +4y crosses over to become -4y,
                                  and -1 crosses over the right side to become +1.
y -4y  = -2/3  + 1
-3y  =    1 - 2/3
-3y =  1/3          Divide both sides by -3.

-3y/-3  = (1/3) / -3.
y  =  1/3  * -1/3
y =  - 1/9
