Answer:

a = 18 units

b = 9√3 units

Step-by-step explanation:

By applying sine rule in the given triangle,

sin(30°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{1}{2}=\frac{9}{a}[/tex]

a = 18 units

Now apply cosine rule in the given triangle,

cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{\sqrt{3}}{2}=\frac{b}{a}[/tex]

[tex]\frac{\sqrt{3}}{2}=\frac{b}{18}[/tex]

b = [tex]\frac{18\sqrt{3} }{2}[/tex]

b = [tex]9\sqrt{3}[/tex] units
