If AB = 9, RS = 3, and SC = 5, find BC.<br> A) 5<br> B) 10<br> C) 13.5<br> D) 15

Ronch [10]

Answer:

Step-by-step explanation:

Δ ABC and Δ RSC are similar triangles, thus the ratio of corresponding sides are equal, that is

$\frac{BC}{SC}$ = $\frac{AB}{RS}$ , substitute values

$\frac{BC}{5}$ = $\frac{9}{3}$ = 3 ( multiply both sides by 5 )

BC = 5 × 3 = 15 → D
