The polygons in each pair are similar. Find the missing side length / first one has 4 &x and second one has 12&18

sergiy2304 [10]

Answer:

x = 6

Step-by-step explanation:

To find the missing side, write a proportion using side lengths from each similar shape. A proportion is an equation that sets equal two ratios.

$\frac{4}{12}=\frac{x}{18}$

Find x by cross multiplying numerator and denominator of each fraction.

4(18) = 12x

72 = 12x
