Answer 1

Since the triangle in question is a right triangle, given the leg lengths, you can use the Pythagorean Theorem to find the length of the hypotenuse.

The Pythagorean Theorem: a² + b² = c², where c is the hypotenuse of the triangle.

Plug in the given leg lengths and solve for c.

               a² + b² = c²
         8.4² + 7.6² = c²
    70.56 + 57.76 = c²
               128.32 = c²
                 11.33 ≈ c

Answer:
11.33 cm
