Answer:

17.32 meters

Step-by-step explanation:

We realize the cable is the hypotenuse and then that height would be the new side, the measurement would not change once hypotenuse is found.

60 deg is the lower angle as it meets the ground base.

Sin (60) = 0.8660254038 x 20 = 17.32m

0.86 reduction = a  

We use Sin (60) = a  a x 20 to find the pole as above.

We use Tan (60) x base to find 20m to check hypotenuse if base was given = length of floor x tan(60) etc.
