Solve using any method. Round your answers to the nearest tenth, if needed. Nautical flags are used to represent letters of the alphabet. The flag for the letter, O consists of a yellow right triangle and a red right triangle which are sewn together along their hypotenuse to form a square. The hypotenuse of the two triangles is three inches longer than a side of the flag. Find the length of the side of the flag.

Key Concepts

Relationship between Diagonal and Side of a Square

In a square, the diagonal forms a right triangle with two adjacent sides as the legs. The length of the diagonal is thus related to the side length by a factor of the square root of 2. This relationship allows one to connect linear dimensions of a square in various geometric scenarios.

Algebraic Equation Solving

Setting up and solving algebraic equations is a key skill when translating geometric relationships into mathematical form. By expressing the known relationships using an equation and isolating the variable, one can determine unknown dimensions or lengths in the problem.

Pythagorean Theorem

The Pythagorean Theorem is fundamental in relating the side lengths of a right triangle. It states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. This concept is essential for solving problems involving distances and lengths where right triangles are present.
