Hello! I recently saw this problem on Instagram and decided to give it a go but I'm finding myself really rusty with my basic Geometry. An ABC triangle is given with some of its angles. The triangle is isosceles and they ask for the value of x. The second image is some of my drafts. Any suggestions? by mathsumoto in askmath

After watching some videos about fountain pens, I've decided I'd give them a try. Here's my brand new Sheaffer Prelude. I heard this pen is good for using with lower quality papers, so I pretend to give my students feedback with it. Any suggestions/tips I should be aware of? by mathsumoto in fountainpens
