X,2x ,6x are the angles..as assumed. Now x+2x+6x =180 Therefore 9x=180 x=20 Now substituting the valye of x in assumption we get all three angles they are 20,40,120.. Hope it helps u mate..

Amit Kumar 9 hours ago

Let the angles be x,2x and 6x. Then, x+2x+6x=180 9x=180 x=20 Therefore; angles are 20, 20×2=40, 20×6=120.

Let a be the first term and d be the common difference of the given A.P. Then,                     
Sm = Sn
{tex}\Rightarrow \quad \frac { m } { 2 } \{ 2 a + ( m - 1 ) d \} = \frac { n } { 2 } \{ 2 a + ( n - 1 ) d \}{/tex}
{tex} \Rightarrow{/tex} 2a (m - n) + {m (m - 1) - n (n - 1)} d = 0
{tex} \Rightarrow{/tex} 2a (m - n) + {m2 - m - n2 + n}d = 0
{tex} \Rightarrow{/tex} 2a (m - n) + {(m2 - n2) - (m - n)} d = 0
{tex} \Rightarrow{/tex}2a (m - n) + {(m  - n) (m +n) - (m - n)} d = 0
{tex} \Rightarrow{/tex} (m - n) {2a + (m + n - 1)d} = 0
{tex} \Rightarrow{/tex} 2a + (m + n - 1)d = 0 {tex} [ \because m - n \neq 0 ]{/tex} ...(i)
