Answer:
D
Step-by-step explanation:
Δ CBA and Δ SAR are similar
Thus the ratios of corresponding sides are equal, that is
[tex]\frac{CB}{SA}[/tex] = [tex]\frac{CA}{SR}[/tex] , substituting values gives
[tex]\frac{5}{x}[/tex] = [tex]\frac{10}{4}[/tex] ( cross- multiply )
10x = 20 ( divide both sides by 10 )
x = 2
Thus
AS = x = 2
