Answers

Answered by abhishekkr20

45° should be the correct answer

Answered by mansigupta23

yes its true beacuse any angle subtracted from 180° then the trignometry function remain same

Ankitsain: how can you explain?

mansigupta23: put any acute value or smaller than 180° it will give eqaul to sinx

ajithanair1966p84qi7: but suppose thr question is as follows

mansigupta23: in what type

ajithanair1966p84qi7: qn: In any quadrilateral ABCD. prove that sin(A+B)+sin(C+D)=0

ajithanair1966p84qi7: can u pps solve th8s

mansigupta23: i can try

mansigupta23: A=B=C=D=90 then sin(90+90)+sin(90+90)=sin180+sin180=0

ajithanair1966p84qi7: but what if A,B,C,D is not 90

mansigupta23: then it make two traingles
