A suitable probability app shows the 1st percentile to be at about 11040 pages.
_____
The app shown has an error in the first decimal digit. The number is closer to 11040.82301. We expect the manufacturer would round to the nearest 10 or 50 or 100 in advertising.
You can't know, because you don't know how big it is on the model
Hello,
Sorry, i don't know the theorem in English
"Théorème des angles extérieurs :
la mesure en degré d’un angle extérieur est égale à la moitié de la différence des arcs interceptés par ses côtés."
Here
2x+15=1/2(10x+20-80)
==>4x+30=10x-60
==>6x=30+60
==>6x=90
==>x=15 °
6 1/2 ÷ 2 3/4
6 1/2 × 2 4/3
6×2 = 12 , 1/2 × 4/3 = 4/6 = 2/3
Answer = 12 2/3
Well I certainly understand why you are having grief. I wonder what we know about this thing? The bottom triangle is easy enough to figure out, but are the lines leading up to it parallel? If they are then 5.2 is not correct, or the right
angle symbol is meant to connect to the vertical line closest to us.
What's all the writing to the left and right. What does it say?
Finally what do you know? Can you find area using Heron's Formula for area. I'm going to hold off saying much. You can put a remark somewhere. The magic editor will pick it up and tell me you've done it.
