Answer:

12.9

Step-by-step explanation:

!!!!

The length of AC is approximately 12.9cm

Triangle identity

Given the following identity

  • Opposite = AC
  • Hypotenuse = 20cm

Using the SOH CAH TOA identity

sin 40 = AC/20

AC = 20sin40

AC = 20(0.6428)

AC = 12.9cm

Hence the length of AC is approximately 12.9cm
