# --description--

最初の経由点において、回転を `110deg` に、スケールの変形は向かって左側の腕に設定されている値そのままに設定してください。

# --hints--

`10%` 経由点の `transform` を `rotate(110deg) scaleX(-1)` に設定する必要があります。

```js
const wave10Percent = [...[...new __helpers.CSSHelp(document).getCSSRules('keyframes')].find(rule => rule?.name === 'wave')?.cssRules].find(css => css?.keyText === '10%');
const rotateProp = wave10Percent?.style?.rotate?.replace(/\s+/g, '');
const transformProp = wave10Percent?.style?.transform?.replace(/\s+/g, '');

if (rotateProp && transformProp) {
  assert(rotateProp === '110deg');
  assert(transformProp === 'scaleX(-1)');
} else {
  assert(transformProp === 'rotate(110deg)scaleX(-1)');
}
```
