Hey there :)
Both the shapes are similar
We can notice that through the angles given
Therefore, we can use ratios to find the segment ZY
WX : EH = 7 : 5
ZY : FG = ? : 7
[tex] \frac{7}{5} = \frac{ZY}{7} [/tex]
We can cross multiply
7 ( 7 ) = 5 ( ZY )
49 = 5( ZY )
Divide by 5 in order to find the answer
[tex] \frac{49}{5} = \frac{5(ZY)}{5} [/tex]
Segment ZY = 9.8
