You are standing 25 feet from a water tower the distances from you to the point of tangency on the tower is 45 feet what is the radius of the water tower

See the picture attached to better understand the problem

we know that
in the right triangle STR
applying the Pythagoras theorem
(r+25)²=45²+r²-----> r²+50*r+625=2025+r²----> 50*r=1400
r=1400/50----> r=28 ft

the answer is
the radius of the water tower is 28 ft 

Hey, can you post the problem?
