Answer:
a(n) = -16b + (n - 1)(3b)
Step-by-step explanation:
First term is -6b.
Common difference is 3b; each new term is equal to the previous one, plus 3b.
Formula for this arithmetic sequence is
a(n) = -16b + (n - 1)(3b)
Answer:
option C
Step-by-step explanation:
m∠3 =m∠6 ( Alternative Interior Angles are equal )
But m∠5 & m∠6 are linear pair. So ,
m∠5 + m∠6 = 180°
=> m∠5 + m∠3 = 180° ( because m∠3 =m∠6 )
