Answer: 
Answer: The value of m is 29.
Step-by-step explanation:
Given that, One term of
is
...(i)
We know that that (r+1)th term in
is given by :-
...(ii)
On comparing (i) with (ii) , we get

i.e.

Hence, the value of m is 29.
3x+5x-12=180
8x=180+12
8x=192
x=192/8
x=24
angle 1 = 5x-12
=5(24)-12
=120-12
=108
angle 2= 3x =3*24=72
angle 1 = angle 9
angle 9= 108
