Hi there!
When I was an apprentice during the probational period at a trading company, I spent almost all my salary going out for a drink with my seniors and coworkers to socialize, except for thirty thousand yen for my parents.
I was a person who was instantly familiar with strangers, so in no time, I could hit it off with my company colleagues right away. That might be the reason why I kicked off my work as an overseas sales representative from scratch.
Our year-end party was always held in a Chinese restaurant that took up positions on the top floor of the building. Drinking Shaoxing rice wine all in one go was our annual event. That would cause a severe harassment problem now if that event had occurred in the Reiwa era in a company.
The alcohol percentage of Shaoxing rice is 14 to 18; however, we had sake such as 40 to 50 alcoholic strength then, which triggered our memory loss at the end of the party. We didn’t have the slightest idea to check the alcoholic content until we broke up the event.
Today, I am in a position to check the degrees of not alcohol but an angle, for I am sober now.
Represent \(\frac{3}{4}π\) in degree measure.
Here is my solution to the problem.
Given that the angle \(\theta\) (rad) is in radian measure and that \(x°\) is the angle in degree measure, 1rad becomes \(1rad = (\frac{180}{π})°\).
Then plug in \(\theta = \frac{3}{4}π\) for \(x° = \theta\,rad×(\frac{180}{π})\).
Thus, \(\frac{3}{4}π = \frac{3}{4}π×(\frac{180}{π})° = \frac{3}{4}×180° = 135°\)
Caution is advised. Don’t be overpowered by mathematics.
Stay tuned, and expect to see my next post.
Keep well.
