Non-Extreme Black Holes from D-branes at Angles

We construct the non-extreme solutions of non-orthogonal intersecting D-branes. The solutions reduce to non-extreme black holes upon the toroidal compactification. We clarify the relation between two configurations with equal mass and charge, one of which is non-orthogonal intersecting D-branes and the other one is orthogonal D-branes, from supergravity and string theory perspective. We also calculate mass and entropies for these black holes.
