Step-by-step explanation:
Δ BDE and Δ BAC are similar, so the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
4AC = 80 ( divide both sides by 4 )
AC = 20
Answer:
WX = 9
Step-by-step explanation:
WY is the entire line - this tells you that the length of the entire line is 11.
XY is a section of the line, and WX is the section you need to find the length for. Since it is given that XY is of length 2, we can find the length of WX by subtracting the length of XY from WY.
11 (WY) - 2 (XY) = 9.
