Step-by-step explanation:
= - 4
= a* + (3- 1) d*
- 4 = a + 2d . . . . . . . . .(i)
= - 29
= a + ( 8 - 1) d
- 29 = a + 7d . . . . . . . . (ii)
subtracting equations (i) and (ii)
25 = 5d
d = -5
placing d = -5 in equation (i)
a - 10 = -4
a = 6
For an arithmetic Progtession
= a + (n - 1)d
= 6 + (n- 1)-5
= 6 - 5n + 5

Step-by-step explanation:
funtion is:
therefore 
is
Now
(Calculation of this it too long and it is hard to type on brainly)

= 4/5
=0.8
Angles 1, 3, 5, and 7 are obtuse angles.
Angles 2, 4, 6, and 8 are acute angles.
1) 1 and 3 are called obtuse.
3) 1 and 7 are also obtuse.
4) 4 and 6 are acute.
5) 4 and 8 are also acute.
hopes this helps a little bit :/
