Video Summary

The problem asks for the missing length in a square with two perpendicular lines and three given segments. By dropping altitudes from both diagonals, two right triangles are formed that are congruent because the diagonals are perpendicular. Let the short leg be \(x\). Since opposite paths equal the square’s side length, we get \(4.8 + x + 7.7 = 6.2 + x + ?\). The \(x\) cancels, leaving the unknown as \(6.3\). So the answer is <strong>D. 6.3</strong>.
