Whoever puts there answer first get brainlest
Anvisha [2.4K]

Answer:

\large Q1:\ x=18\ ft\\\\Q2:\ 6\ inches

Step-by-step explanation:

Q3.

If ΔGHI and ΔJKL are similar, then the sides are in proportion:

\dfrac{JL}{GI}=\dfrac{LK}{IH}

We have

JL = x, GI = 9 ft, LK = 24 ft, IH = 12 ft.

Substitute:

\dfrac{x}{9}=\dfrac{24}{12}

\dfrac{x}{9}=2         <em> multiply both sides by 2</em>

x=18\ ft

Q4.

We must multiply the original length by a scale factor of 3/4:

\dfrac{3}{4}\cdot8\ in=\dfrac{3}{1}\cdot2\ in=(3)(2)\ in=6\ in
