Given:

Given that ABC is a right triangle.

The measure of ∠A is 32°.

The length of AC is 9 units.

The length of BC is x units.

We need to determine the value of x.

Value of x:

The value of x can be determined using the trigonometric ratio.

Thus, we have;

[tex]sin \ \theta=\frac{opp}{hyp}[/tex]

where θ = A, the side opposite to A is BC and hypotenuse is AC.

Thus, we have;

[tex]sin \ A=\frac{BC}{AC}[/tex]

Substituting BC = x and AC = 9, we get;

[tex]sin \ 32=\frac{x}{9}[/tex]

Multiplying both sides by 9, we have;

[tex]sin \ 32 \times 9=x[/tex]

         [tex]4.77=x[/tex]

Thus, the value of x is 4.77 units.
