Answer:
Notice the line in between the 61 degrees and b
Step-by-step explanation:
I can't remember what this kind of angle is called, but when you have a straight line with another line coming out of it like this, then the sum of both angles has to equal 180 so what would you add to 61 to get to 180?

Answer:
18 terms
Step-by-step explanation:
The first given sequence has first term a1=2 and common difference d=5. Its explicit formula is ...
an = 2 +5(n -1) = 5n -3
We want the n-th term of this sequence to be the same as the n-th term of the sequence defined by ...
an = 4n +15
We can find n that makes this true by setting the 'an' values equal:
an = an
5n -3 = 4n +15
n = 18 . . . . . . . . . . add 3-4n
The number of terms in each sequence is 18.
