You can put this solution on YOUR website! I cannot get to see the picture.
K12 wants me to "sign in" to let me see it.
However, when side length are given,
the most popular right triangle shape is
that of 3-4-5 triangles.
That is because 3,4,5 is the first Pythagorean triple,
and the only one remembered by most teachers and students.
The right triangles with that shape have side length
3, 4, and 5, or
6, 8, and 10, or
9, 12, and 15, or
12, 16, and 20, or
15, 29, and 25, or
3n, 4n, 25n for any positive n.
I bet your triangle wad one of those.
