Best ResponseYou've already chosen the best response.1six digits in the triangle>Let T =6 eight digits in the rectangle>Let R=8 Total = 10 digits. = T union R (in other words, T OR R) get this much ?

Best ResponseYou've already chosen the best response.1how do u get 10 digits?

Best ResponseYou've already chosen the best response.10 to 9 means total 10 digits i assumed that the digits are not repeated, which is a fair assumption here...

Best ResponseYou've already chosen the best response.1ohk...no they not repeated

Best ResponseYou've already chosen the best response.1digits are in the part that belongs to "both" figures = T AND R (T intersection R) = ...... there is a formula for this, you know ? in terms of T,R and T UNION R

Best ResponseYou've already chosen the best response.1now look at that figure, if u want total area of composite figure, will it be appropiate to add the area of triangle and rectangle ?

Best ResponseYou've already chosen the best response.1by the area of composite figure do u mean the overlapped shape?

hartnn

Best ResponseYou've already chosen the best response.1yes,. because then you will consider the "intersection part" twice. once in rectangle and once in triangle, got this ?

hartnn

Best ResponseYou've already chosen the best response.1so to get area of composite figure, u need to subtract are of intersection, right ?

hartnn

Best ResponseYou've already chosen the best response.1so , we get TOTAL = RECT +TRIANGLE  INTERSECTION. in this case, total = 10 , Rect = 8, triangle =6 u just need intersection

hartnn

Best ResponseYou've already chosen the best response.1so, 10 = 8+6x where x is digits that belongs to both figures

Best ResponseYou've already chosen the best response.1yes, so there are 4 numbers that belong to both..
