Answer 1

$Jl/PQ = JK/PR \: \: (BPT) \\ </p><p>21/14=x/20 \\ </p><p>2x=60 \\ </p><p>x=30$

Answer 2

Answer:

In triangle PQR the sides are 12,14,20

there ratio is 6:7:10

The polygons are similar so the triangle JKL also has the ratio of its sides as 6:7:10

6x=18. 7x=21

x=3. x=3

So, 10x=10×3=30
