# --description--
|
|
|
|
Let us call an integer sided triangle with sides $a ≤ b ≤ c$ barely obtuse if the sides satisfy $a^2 + b^2 = c^2 - 1$.
|
|
|
|
How many barely obtuse triangles are there with perimeter $≤ 75\\,000\\,000$?
|
|
|
|
# --hints--
|
|
|
|
`almostRightAngledTrianglesTwo()` should return `4137330`.
|
|
|
|
```js
|
|
assert.strictEqual(almostRightAngledTrianglesTwo(), 4137330);
|
|
```
