Answer:

Answer is 9.6

Step-by-step explanation:

From the illustration above. See attachment for interpretation of this illustration.

To find the part label a in the attachment which is the length of the foot of the guide wire from the ground to the palm tree, we apply the sine rule, which says

a/sineA = b/sineB

In this case

a = ? , A = 58° , b = 6ft, B = 32°

So

a/sine58 = 6/sine32

a/0.848 = 6/0.5299

a = 6*0.848/0.5299

a = 5.088/0.5299

a = 9.601 ~ 9.6
