Please help !! Will mark brainliest answer
Norma-Jean [14]

Answer:

x = 12

Step-by-step explanation:

18:24 (comparing the same sides for the similar shapes; 18 and 24) when simplified down is equal to 3:4.

Using this 3:4 scale factor we can find the missing side x.

Solving for x :

\frac{3}{4} × 16 = 12

x = 12

OR: Set up a proportion:

\frac{24}{16} × \frac{18}{x}

<em>cross-multiply</em>

16 × 18 = 288

24 × x = 24x

288 = 24x

x = 12
