I need help with this math if u can I'll give you credits, thank you!


Answer: w= 9.6cm
Step-by-step explanation:
By the figure two triangles are similar
so 16/16+4 = w/12
2DW= 16 x 12
W= 16 x 12/20 = 9.6 cm
Two triangles are similar and the corresponding sides are proportional.
Hope this helped! <3
