Find the approximate side length of a square game board with an area of 122 in^2.

Use set buikder notation to represent the following set: {, -2, -1, 0}

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.

The sum of the squares of two numbers is 8 . the product of the two numbers is 4. find the numbers.
