I attached a picture, see if you can see what I'm doing. Basically, I start by squaring everything to get rid of the radical, but just remember at the end to always, always check your answers, because squaring your answers could get rid of some negative numbers that could result in imaginary answers. The answer I came up with was a=5,-2
Use similar triangles
distance of man from puddle = 0.5 m.
distance of puddle from tower = 13 - 0.5 = 12.5 meters
so we have 2 similar triangles
one has height 2 m and base 0.5 m and the other has height x m ( the tower) and base 12.5 m
Corresponding sides are in the same ratio, so
2 / x = 0.5 / 12.5
0.5x = 2*12.5 = 25
x = 25 / 0.5 = 50 m
The tower is approx 50 m high.

Step-by-step explanation:
Subtracting the right side gives ...
The factor multiplying y cannot be zero, so y must be zero.
