Answer:
Explanation:
notes on the figure
1. the left pole equals to 12 m(5+7)
2. the right pols equal to 7m
3. the lower distance between them is given that is 12m
4. a triangle is formed above the rectangle formed by them
the triangle ABC is a right-angled triangle
by Pythagoras
(ac)^2=(ab)^2+(bc)^2
ac^2=5^2+12^2
ac^2=25+144
ac^2=169
ac=root 169
ac=13m
their distance is 13m
