Simplify the following union (-∞,4]n[0,15)

Hey Steve what's up

I would like to correct you, that it's intersection not union union had u typed symbol whereas intersection had inverse u typed structure.

Hence here the intersection is {1,2,3,4}

Thank you

Good day Steve

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
