# --description--

How many triangles are there with integral sides, at least one integral angle (measured in degrees), and a perimeter that does not exceed ${10}^8$?

# --hints--

`trianglesWithIntegralSidesAndAngle()` should return `416577688`.

```js
assert.strictEqual(trianglesWithIntegralSidesAndAngle(), 416577688);
```

# --seed--

## --seed-contents--

```js
function trianglesWithIntegralSidesAndAngle() {

  return true;
}

trianglesWithIntegralSidesAndAngle();
```

# --solutions--

```js
// solution required
```
