Answer:
- 1020
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = a₂ - a₁ = 0 - 12 = - 12 , thus
a₈₇ = 12 + (86 × - 12) = 12 - 1032 = - 1020
Answer:
2a+110=180(co interior angle)
2a=180-110
a=70/2=35
2a=2×35=70
a=x=35 alternate angle
x+2a=y exterior angle of triangle is equal to the sum of two interior angle
35+70=y
y=105
