It's a trap. The drawing is misleading. If the left triangle already has 60° and 40° then only 80° remains. Meaning there's no right angle. The vertical line should be leaning to the left slightly. The correct answer is 135°.
People tweeting stuff. We allow tweets from anyone.
RULES:
Mark NSFW content.
No doxxing people.
Must be a pic of the tweet or similar. No direct links to the tweet.
No bullying or international politcs
Be excellent to each other.
Provide an archived link to the tweet (or similar) being shown if it's a major celebrity, figure or any politician. If you replace the "x" at their site with xcancel (so it beomes xcancel.com), and you're not on mobile, it will save video. https://web.archive.org/save is another great option. Archive.is is no longer recommended because they remove/alter content.
