anonymous · Answer

it is 24

@Akpellet_math how did you get that?

idk how to do it im so confused

anonymous · Answer

$$\frac{ ST }{ WB }=\frac{ TC }{ BL }=\frac{ SC }{ WL }$$

ranga · Answer

In similar triangles, corresponding sides are proportional.

anonymous · Answer

here 
WL/WB = SC/ST 
or WL = 20* 30/25 =24

anonymous · Answer

put values in that and solve.!

ok. thanks guys!!
