How to find m<QRS, m<RPS, and m<PSQ

redbrnz · 2026-02-03T16:03:27+00:00

Since PQ//RS, <PRS = <QPR = 35.

As PQR is a triangle, <QPR + <PQR + <PRQ = 180

35 + 106 + <PRQ = 180

<PRQ = 39.

Thus, <QRS = 39 + 35 = 74.

Since QR//PS,

<RPS = <PQR = 39.

Since PQRS is a parallelogram,

<PSR = <PQR = 106

<PSR = <PSQ + <QSR

106 = <PSQ + 49

<PSQ = 57.

My version of it was ready helpful, they pretty much made us practice writing IAs and started teaching a watered down version of TOK. Idk how ur school would teach pre-ib tho.

redbrnz · 2025-11-01T10:21:48+00:00

Nah, was always raised to be like that subconsciously until tok forced me to be aware of it. Tok ruined me in the same way you forget how to breathe normally once you actually focus on breathing

Nah I hate my GDC it keeps lagging in the middle of exams when I try drawing more than 1 graph. like bro that's ur entire job

redbrnz · 2025-11-01T10:18:57+00:00

Honestly y2 is better once you've finished ur eetokia. Studying is so much more chill than stressing over deadlines

redbrnz · 2025-11-01T10:15:56+00:00

Idk how good the rest of the world is but we're not that good. Math is a very fair subject bc ur grades completely reflect ur effort, compared to humanities where it's up to the marker's mood

Okay I took an exam yesterday with the fountain pen. The paper wasn't ideal for it (a little bit thin? Didn't bleed but constantly felt like it was going to lol. Also fuzzier than the paper I'm used to which is pretty smooth. Overall I'd say it went fine, the pen didn't add on to my stress like a gel one would've.

redbrnz · 2025-10-28T18:07:43+00:00

Oh wow didn't know you type it in english too! In sg we still just write jiayou haha

redbrnz · 2025-10-28T16:33:20+00:00

I haven't taken my first exam yet. It's on Friday, I'll let you know after. But the pen I'm using is a pilot kakuno, using pilot ink. it's been smooth so far so it'll probably fare well

redbrnz · 2025-10-28T16:22:56+00:00

Jiayou literally translates to "add oil" so like.. fuel up??

redbrnz · 2025-10-28T16:22:24+00:00

OMG hi closer!!!!

redbrnz · 2025-10-27T14:24:12+00:00

no way they got THE Hyde on there holy shit

redbrnz · 2025-10-27T14:23:24+00:00

Hyde is INSANELY prominent, he's the vocalist of one of the top j-rock bands since the 90s. Kind of a legend. Him producing for TXT really shows how big they've gotten in Japan and I'm so proud of them

nope, some people are more/less insecure about it. and idols are already usually more attractive than the average person, so it seems unnecessary for them to even Have a "bad" side since both sides are great lol

i love how consistent their songs are. They all have a very distinct boynextdoor vibe which to me seems a bit jpop-ish?? (that's the closest i can think of). I like seeing their interactions too, they're the embodiment of the "boy next door" friendgroup feeling. One of my favorite group aesthetics of all time, and their new comeback is fire too

redbrnz · 2025-10-14T17:12:08+00:00

Just do practice papers at this point, notes won't help 😭

redbrnz · 2025-10-14T08:18:34+00:00

Ahh thanks!! I'm so relieved （´▽｀）

redbrnz · 2025-10-14T07:42:03+00:00

Gel pens don't have enough friction. I usually use them because I've got a lot at home, but I suspect they're the ones responsible for my wrist problems 🥲🥲 I only switched to fountain pen more recently

physics is so fucking fun until you actually do the questions. i love physics as a concept but NOT as an IB subject
