Answer:

1) given

sum of two angle of triangle= 150 degree

let third angle be x

angle a + ang. b + ang.c = 180 deg.

150 deg. + x = 180 deg.

x = 180 deg. - 150 deg.

x = 30 deg.

2) let no. be x

acc. to statement

4 + 3x = 12 + 2x

3x - 2x = 12 - 4

x = 8

3) I don' t know about this

4) No one's statement is correct because away said that one linear equation have answers but it has one answer and Suman said that every equation have same answer but every equation have different answer according to statement
