Part (A): Since the two figure are similar, therefore, we will use the similarity proportionality to get the unknown side as follows: [tex] \frac{16}{8} = \frac{x}{2} [/tex]
x = [tex] \frac{2*16}{8} = 4 units[/tex]
Part (B): Since the two figures are similar, therefore, we will use similarity proportionality to get the unknown sides as follows: [tex] \frac{y}{8} = \frac{12}{4} = \frac{18}{x} [/tex]
