Answer:
D 3500
Step-by-step explanation:
This question is asking for the sum of all the terms in an arithmetic series.
So using the formula : Sn = n/2 (a+l) , where Sn is the sum of n terms, a is first term, and l is last term, we try to find Sn, with n being 25, a being 20, and an which is a25 or the twenty fifth term being 260, also being the last term.
Hence we can produce the formula for Sn which is Sn=25/2 (20+260)
Sn=25/2 (280)
=3500
Answer:
x = 90
Step-by-step explanation:
2(45° ) + x = 180°
Distribute
90 +x = 180
Subtract 90 from each side
90+x-90 =180-90
x = 90
