Step-by-step explanation:
Sn = n/2 (a1+an)
= 8/2 (3-38)
= 4 (-35)
= -140
Answer:
I think the answer may be 465
Step-by-step explanation:
105+115=220
150+95=245
245+220=465
Answer:
r = 23
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
5 = (3 - r)/(-8 - (-4))
5 = (3 - r)/(-8 + 4)
3 - r = 5 × -4
3 - r = -20
-r = -23
r = 23
Answer:
y ≈ 5.63
Step-by-step explanation:
m∠KLN and m∠NLM have to add up to m∠KLM
m∠KLN = 47°
m∠NLM = 16y°
m∠KLM = 137°
47 + 16y = 137
16y = 90
y = 45/8
y = 5.625
y ≈ 5.63
