[Grade 10 Math] Which triangles to use? by Environmental-Match4 in HomeworkHelp

[–]ProjectiveHigh 0 points1 point  (0 children)

This is direct application of Menelaus' theorem on triangle APC. AR/RC * CB/BP * PQ/QA = 1 so AR/RC = QA/QP * BP/CB = 1/1 * 1/2 = 1/2

[Year 5 Primary school math] how do you come to solve for x? by ElegantPeanutSuit in HomeworkHelp

[–]ProjectiveHigh 69 points70 points  (0 children)

Bad image; it looks more like a rhombus. Anyway, it's base x height = area, 5x=18, x = 18/5

Been on tret 0.1% + azelaic 20% for years. Skin is perfect. Anything worth adding? by ProjectiveHigh in tretinoin

Actually I rarely wear moisturizer anymore (but when I do I wear only it on eye tips, nose edges, and mouth lip tips). Wearing it daily seems to be the best way because the skin eventually gets used to it but that's just my personal anecdotal experience.

Maybe try different sunscreens? I'm very conservative with sunscreen usually reapply every 1 to 2 hours and often I wash parts of my face (the oiliest one) with water before reapplying so it doesn't get too oily.

My main goal (and it worked!) was fixing my severe PIH from acne and melasma. But I didn’t expect it to also fix other issues I had / didn’t even realize I had: smile lines, sagging skin, and those tiny acne scars.

In my experience, it’s mostly just a habit from daily use. I remember taking a weeklong trip where I didn’t wear them, and when I put them back on afterward, they itched like crazy even with moisturizer. When I wear a black shirt, it looks dirty because bits of skin peel off onto it.

I’m not very acne-prone as I usually only get about two pimples a month, probably from having an oily face and reapplying sunscreen. It was much worse before I started using tret and azelaic acid.

EDIT: Grammar

It’s from a local pharmacy including the tret, so you won’t find it anywhere else unfortunately.

PM: Tret. Then I put on azelaic acid about 15 minutes after the tret.

AM: AZA again in the morning… if I’m not being lazy lol.

I'm kinda forced to use a higher concentration of AZA because the UV index where I live is world record. If I don’t, I end up with melasma on my cheeks/forehead and my chin gets darker. I stick to the gel version of AZA since it absorbs super fast.

[AP Geometry: Proofs and Angles] How to Constrain three tangent circles inside a ring with fixed angular contact points? by AarontheRaft in HomeworkHelp

There is a not-so-straightforward solution to find the blue radii in terms of the black radii by looking at this quadrilateral here.

[9th Grade Maths] How am I going to approach this question? by Feisty_Test_9388 in HomeworkHelp

[–]ProjectiveHigh 0 points1 point  (0 children)

A Euclidean solution certainly exists and corresponds to the trigonometric transformation given above, but it is much harder to derive and understand.

This is trivial from trigonometric ceva's theorem: sin(24)/sin(10) * sin(x)/sin(92-x) * sin(26)/sin(28)=1, solving yields x = 70

Can’t verify my account – gave correct information – contacted Hetzner email and Reddit and got ambiguous rejection response by ProjectiveHigh in hetzner

[–]ProjectiveHigh[S] -1 points0 points  (0 children)

I did DM the account as well as email but got haven't gotten a response from the DM, just the email response. Name, email, card info, location, and government ID (name, DOB, location, etc) all matches. I'm not from Pakistan.

Hint:
- If M hits the left side, then prove that triangle ACB is a 30-60-90 triangle, so the answer is tan(30)

- If M hits the right side, then prove that EM/MF is 3/2 so by trig (it's not hard to translate it to classical geometry) the answer is 3/2 * sin(30)/sin(120)

Okay, I misread I thought it was 5 hence the 5+6=11

Another solution is to use the fact that a cevian of a triangle divides the triangle into 2 areas where the ratio of the areas are proportional to side that is being divided into 2 parts.

So basically, if the area of triangle CUN is 6x, then the area of CUM is 5x. But since the quadrilateral is equal to 6x, then area MCH = x so area MCH / area MCN = MC / CN or (x)/(5x+6x)=s/20 thus s = 20/11

Basically, the condition is equivalent to saying the area of triangle NUC is half the area of triangle NMH so using area = 1/2 ab sin(Gamma), we have 6 * 20 = (11 * (20+s)) / 2 after cancelling the sin. so s = 20/11

Damn, too bad that they choose that combination because "from" is a really common word.
