Math Problem Statement

Quadrilateral GHJI is similar to quadrilateral KLMN. Find the measure of side KL. Round your answer to the nearest tenth if necessary.

Solution

Given thatAlright quadr!ilateral I ( see GH theJI problem. We're given that \ quadr)ilateral is GH similarJI to is quadr similar to quadrilateralilateral K (LM KNLM, andN we \ need to find the), length of side we can ( use the KL concept \ of).

Given similarity:

  • to ( GH = find 5 \ the)
  • HI measure of = side \( KL1 \.

) Similarity- means ( IJ = the7 corresponding \ sides) of the two quadril-aterals are ( proportional. J Let's set upG the proportion using = the corresponding sides :

-3 GH \ corresponds to)

( KL \And)

  • ( for H theJ \ similar) quadr correspondsilateral: to- \( MN = LM32.3 \

Since the) quadril-aterals are similar , J the sidesI are proportional \. We can) set up a proportion corresponds using corresponding sides to. Let's \( match \( MN GH \ with) - KL \( \ IG) \ and \() MN corresponds \ to) \( with NK \(

To solve for xx: x=5×32.37x = \frac{5 \times 32.3}{7}

Calculating this: x23.1x \approx 23.1

So, the length of side KLKL is approximately 23.1 units.
