Let's say that BC is x, so that AB is 4x, and AE = y.
The shaded area then is represented by 4xy/2 = 2xy.
The total area is represented by (4x+x)*y = 5xy.
The fraction of these is 2xy/5xy = 2/5.
Chocolatey107 is right!
So is 4 floors / 10 seconds
If you have 60 seconds you can multiple 10 by 6 because 10×6=60
so you also have to multiple 4 by 6
4×6=24
and because it's descending it's 100-24= 76
14 km I don’t know somethings I have to do it hypothesis
Hi! So, here’s what I know. Every triangle will equal to 180*. So to check if that triangles is 180 we add all angles and it should add up to 180*.
Now the question is, Why it shows that the angles of a triangle equal to 180* when added up?
Note that we see all angles lie on a straight line, therefore we know that when we add angles that lie on a straight line it will equal to 180*, they will also meet at the same point.
This is all I can help with. Hope it helped something!!! Have a great day!
Actual distance = distance on map x the scale:
3 inches x 15 miles per inch = 45 actual miles.
