i have the rs aggarwal book, i want u to explain it to me and pls clear the angle concept to me why the sum is not coming 360. it is related to same ques. i have solved it in a different way. let one be x.so other will be 180-x. now x/2 and 90-x/2. nowif we will add x/2+90-x/2+x/2+90-x/2 we will not get 360. 360 must come coz sum of angles of a rectangle is 360.
pls i have GEOMETRICAL MATHEMATICS SECOND FORMATIVE SCHOOL BASED ASSESMENT
