+839 Find the measures of the angles of a right triangle CDE in which the tangent of <C is 1.
+130515 If the tangent is 1, the opposite and adjacent sides are the same. And in any triangle, if two sides are equal, the angles opposite those sides are equal. And since we have a right triangle, one angle = 90 and the other two would have to sum to 90 as well. And, since they're equal, each must be 45 (degrees).
Does that make sense???
