Question

If KM ll JN, then find the value of J.

  1. 11.25
  2. 10.25
  3. 9.25
  4. 6.25

hintHint:

If a line is drawn parallel to any one side of a triangle so that it intersects the other two sides in two distinct points, then the other two sides of the triangle are divided in the same ratio.

The correct answer is: 11.25


    Triangle proportionality theorem
    24 over 15 equals fraction numerator 18 over denominator K J end fraction
K J equals fraction numerator 18 cross times 15 over denominator 24 end fraction equals 45 over 4 equals 11.25
    Hence, the correct option is A.

    It is also called basic proportionality theorem.
