@Threatter No, you are wrong. You are assuming things from a drawing, which is a very bad thing to do. Where is it claimed that for example EFGB are on one line? Angles are not used and not needed in this example at all.
Late but,let's see if I can help. So , basically in the star we only have to measure the perimeter of the star " ⭐" and not what lies inside so the outer perimeter will do
The answer to the first problem (the star) is wrong. The angle of the pentagon is 108°, therefore the angle in the triangle must be 180° - 108° = 72° The perimeter of FGHIJ is 50, so the length of FG is 10. If the perimeter of AGF is 30, then the length of AF and AG must be 10. This means that the triangle is equilateral, all angle must bee 60°. So to sum up: The correct answer is that the problem is unsolvable. Your answer is incorrect.
@Threatter the angles arent mentioned at all, they can easily be different angles and different length sides, it is just total perimeter given

2:28 " ...and we're done". I wish it seemed that easy to me.

The last problem... From the diagram, it's not shown that the "other" 2 side is 2 in length. Other than that, great video!
Your the best thanks for teaching us
I hate math, but sometimes I love math...idk why. Is it just me or?
Your not alone
Same here
CONGRATS ON 3 MILLION!!!
great work
Thanks
5*30-50=100
what program are you using?
I realise in three years this hasn't popped back into your mind one time, but Sal uses Smoothdraw. It's a free program.
