If ΔEFG ~ ΔLMN with a ratio of 2:1, which of the following is true?
strojnjashka [21]

Answer:

  segment EF over segment LM equals segment FG over segment MN

Step-by-step explanation:

The triangles are similar, not congruent, so any answer choice with the word "congruent" can be ignored.

The sequence of letters in the triangle name tells you the corresponding segments:

  • EF corresponds to LM
  • EG corresponds to LN
  • FG corresponds to MN

Corresponding segments have the same ratio, so ...

  EF/LM = FG/MN . . . . . . matches the first answer choice

  EF/LM = EG/LN . . . . does not match the 3rd answer choice

PLS ANSWER THE BELOW QUESTION AND I'LL MARK U AS BRAINLIST
MA_775_DIABLO [31]

Answer:

Step-by-step explanation:

a) \dfrac{3x}{2}-5=4

Add 5 to both sides

\dfrac{3x}{2}-5 +5 = 4 + 5\\\\\dfrac{3x}{2} = 9 \\\\Now \ multiply \ both \ sides  \ by  \  2 \\\\\dfrac{3x}{2}*2 = 9*2\\\\3x = 18\\Now \ divide \ both \ sides  \ by \ 3\\\\x =\dfrac{18}{3}\\\\

x = 6

b) \dfrac{x-3}{5} + 1 = -2\\\\\\Subtract \ 1 \ from  \ both \ sides\\\\\dfrac{x-3}{5} = -2 -1\\\\\dfrac{x-3}{5} = -3\\\\Multiply \ both \ side \ by \ 5\\\\x - 3 = -3*5\\\\x -3 = -15\\\\

Add 3 to both sides

x = -15 +3

x = -12
