Final answer:

To find ad, we use the sine function in triangles ABC and ACD. We find that ad is approximately 1.154 cm.

Step-by-step explanation:

To find ad, we need to find the length of ad. Since triangle ABC is a right triangle with angle ACB = 90°, we can use the sine function to find the lengths of the sides. Let's use side bc as the reference and apply the sine function in triangle ABC:

sin(ACB) = bc / ac

sin(90°) = 6 / ac

Since sin(90°) = 1, we have:

1 = 6 / ac

ac = 6

Now, let's use side cd as the reference and apply the sine function in triangle ACD:

sin(ACD) = cd / ad

sin(60°) = 1 / ad

ad = 1 / sin(60°)

Using the value of sin(60°) ≈ 0.866, we have:

ad ≈ 1 / 0.866

ad ≈ 1.154 cm
