Hello :
the nth term ( general term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d , A1 : the first terme
A1 = 5 and : d = 1 - 5 = - 4 n = 21
A21 = 5 + (21 -1)(-4)
A21 = 5 - 80 = -75

Answer:
41
Step-by-step explanation:
supplementary angle is 180
therfore to fin
d the answer =
180-139=41
Answer:
2 2/3
Step-by-step explanation:
5+2=7 which means there will be 7 zeros so it is 10000000 times greater than
I'm pretty sure this is Triangle stuff, with Sin, Cos + Tan, etc.
I can't remember it all I'm afraid, but the angle will be the 1 degree, 10 minutes - the Hypotenuse side will be the 3.5 km
