Answer:
UY = 90
GH = 4
Explanation:
Given that FGHIJ ~ YUVWX, therefore, their corresponding side lengths would be proportional to each other. Thus:
UY/GF = VW/HI
UY/10 = 63/7 (Substitution)
UY/10 = 9
UY = 10*9
UY = 90
In the same vein, we have:
VW/HI = UV/GH
63/7 = 36/GH (Substitution)
9 = 36/GH
GH*9 = 36
GH = 36/9
GH = 4
