Convergent

Step-by-step explanation:

aₙ = 2ⁿ / n!

aₙ₊₁ = 2ⁿ⁺¹ / (n+1)!

lim(n→∞)│(2ⁿ⁺¹ / (n+1)!) / (2ⁿ / n!)│

lim(n→∞)│(2ⁿ⁺¹ / (n+1)!) × (n! / 2ⁿ)│

lim(n→∞)│(2ⁿ⁺¹ / 2ⁿ)  × (n! / (n+1)!)│

Notice that (n+1)! = (n+1) n!.  So this reduces to:

lim(n→∞)│2 × 1 / (n+1)│

0

The limit is less than 1, so the series is absolutely convergent.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
