Answer:
AC = 17.8
Explanation:
to figure out the length of AC, you want to put the values into the tangent function:
tan 64° = AC/8.7
Now to solve:
first swap them so you have AC/8.7 = tan 64°
Multiply both sides by 8.7 to get AC = 8.7 tan 64°
then calculate it
AC = 8.7 x 2.0503...
AC = 17.8376
AC = 17.8 (3 Significant Figures)
