Someone help me on this please!

Answer:

x = 15 cm

Step-by-step explanation:

All the ratio of corresponding sides should be equal

10 corresponds to x

16 corresponds to 24

12 corresponds to 18

Finding the ratio of the known pairs:

$\frac{16}{24}=\frac{2}{3}$
$\frac{12}{18}=\frac{2}{3}$

Similarly 10 is to x should be 2 is to 3. Finding x:

$\frac{10}{x}=\frac{2}{3}\\10*3=2x\\30=2x\\x=\frac{30}{2}\\x=15$

So x = 15.
