Mrs. Santos wants to purchase a cover for their circular pool. She needs to know the radius of the pool, but she does not want to get wet to take the measurements. She is standing 1.5 meter from the pool and 4.5 meter from the point of tangency. Find the radius of the pool.

Use Pythagoras' theorem. 

 

One leg of the right-angled triangle is r(the radius); the other leg is 4.5; the hypotenuse is (r+1.5).

I think one leg is the radius       One leg is the radius + 1.5     and the hypotenuse = 4.5 m
