Nat2105 [25]

Using the principle of parallel lines, the value of x in the given triangle is calculated to be 8

<u>The</u><u> </u><u>smaller</u><u> </u><u>triangle</u><u> </u><u>can be</u><u> </u><u>expressed</u><u> </u><u>as</u><u> </u><u>:</u>

  • Side / base = 6/x ----(1)

<u>The</u><u> </u><u>larger</u><u> </u><u>triangle</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>expressed</u><u> </u><u>as</u><u> </u><u>:</u>

  • Side / base
  • Side = 6+9 = 15
  • 15/20 - - - - - (2)

<u>Equating</u><u> </u><u>(</u><u>1</u><u>)</u><u> </u><u>and</u><u> </u><u>(</u><u>2</u><u>)</u><u> </u><u>:</u>

6/x = 15 / 20

15x = 20 × 6

15x = 120

x = 120 / 15

x = 8

Therefore, the value of x in the triangle is 8.
