Answer: Tangelos are a cross between tangerine and grapefruit. The hybrid 'Minneola' tastes more like a tangerine; the hybrid 'Sampson', tastes more like grapefruit. Sounds as though you've got the more tart of the two trees. There's not much you can do to make the fruit sweeter, except to add sugar when you eat it. Tangelos are mostly used for making marmalade and juice, not for eating straight off the tree.
