If the odds of Mr. Abel beating Mr. Brown at a game of chess are 2:1, what are the odds of Mr. Brown beating Mr. Abel in a 5 game series? Remember, as soon as someone wins 3 games, the series

is over.

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.

Math each whole number with a rational,exponential expression

In δabc, m∠acb = 90°, cd ⊥ ab and m∠acd = 45°. find: a find cd, if bc = 3 in
