Answer:
y = 5[tex]\sqrt{3}[/tex]
Step-by-step explanation:
using the tangent ratio in the right triangle and the exact value
tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then
tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{5}{y}[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )
y = 5[tex]\sqrt{3}[/tex]
