wtf how do you solve this

with vectors

True
Lines 3 and 4 are parallel so you can state the congruency of the bigger triangle and triangle with side A through SAS
Q.E.D.

Make more triangles. With trig/geometry the answer is always just make more triangles. I'm not gonna bother going through it but here:
Ian Parker
- Decompose into smaller triangles.
- Find every possible angle and length using trigonometry.
- Use sine and cosine rules if needed.
- ???
- Profit.
Levi Phillips
Might've gotten something wrong, but I think the idea is enough
Daniel Nguyen
Unless I've made a mistake, you shouldn't need trig for this, it's solvable with elementary geometry. Wrt. pic related:

I went a different route from you after step 2. Instead I extended PU to meet line A (let's call the intersection X), so AS ⟂ PX. In addition, also have a point Y on PU such that PY ⟂ QY. We have VR + RS = 12/7 + 7 = 61/7, and since ∠QPY = ∠ SVX and ∠PYQ = ∠VXS, it follows that we have two similar triangles so SX = 61/7 * 3/4 = 183/28, which is what you got.

imagine wasting your time thinking of triangles instead of doing something useful.

At least update it to a version with better configuration and settings, unless your PC is just too shit to run that.

Triangles are the strongest shape, why would you waste time on any other shape you mongoloid
Robert Foster
you are using triangles right now
David Bell
Thanks! I had suspected that there would be a faster solution after drawing out all the lines, but somehow it didn't occur to me to use the similarity of PYQ and VXS directly.
I think that your solution is about as succinct as we can go, though.
Adrian Parker
combination of it does what I need but also yes my comp is probably too shit to update, I'm on 2017 at work though but I mainly use solidworks anyways
Dylan Nguyen
I'm guessing inches?
Andrew Jones
>haha triangle strong
>add more triangle
you're not even right though faggot. The strongest shape is a semi-circle
Adam Cooper
I sucked at math

triangles paved the way for finding distance in the second dimension and onwards

I've gotten worse at AutoCAD in recent years because my workplace is wanting people to use Adobe Inventor for things it shouldn't even be used for
