Answer:
x = 7
Step-by-step explanation:
To find the missing side, write a proportion using side lengths from each similar shape. A proportion is an equation that sets equal two ratios.
[tex]\frac{4}{8}=\frac{-7+2x}{14}[/tex]
Find x by cross multiplying numerator and denominator of each fraction.
4(14) = 8(-7+2x)
56 = -56 + 16x
112 = 16x
7 = x
