Answer:
x = 6
Step-by-step explanation:
Since <F = <F, this shows that the triangles are similar. Therefore:
XZ/DF = XY/DE
12/8 = 9/X
Cross multiply
12X = 9*8
12X = 72
X = 72/12
X = 6
Hence the value of x is 6

Answer:
100%+15% = 115%
proportionally:
x - 100%
161 - 115%
x = (161 * 100%) / 115% = 140
