Answer:
14.31m
Explanation:
There are 2 triangles made and we will use pythagoras in each.
The hypotenuse of first triangle will be base for 2nd triangle.
Hypotenuse)^2 = 5^2 + 12^2
Hypotenuse = 13m
Now, in other triangle hypoteuse = square root of 6^2 + 13^2
= square root of 36+169=205
= approximately 14.31 m
