Answer 1

18 ft

Explanation:

Height of the cable pole and it's shadow's length will be in direct proportion with the height of man and its shadow.

Let the height of the cable pole be x feet

`\therefore (x)/(12) = (6)/(4) \\ \\ x = \frac{ \cancel{12} * 6}{ \cancel4} \\ \\ x = 3 * 6 \\ \\ x = 18 \: ft`
