Answer:
Step-by-step explanation:
We have two sides; the Adjacent and the Hypotnuse
Meaning we will use Cos
Cos = A/H
Cos X = 16/19
Use the inverse of Cos to find the angle
X = cos-1 (16/19)
X = 0.45499141546
X = 0.45

Answer:
26,244
Step-by-step explanation:
The sequence is geometric with a common ratio of -3. The general term is ...
an = (a1)r^(n-1)
The first term is 4, so we have ...
an = 4·(-3)^(n-1)
For n=9, we find the 9th term to be ...
a9 = 4·(-3)^(9-1) = 4·3^8
a9 = 26,244

<em>Additional comment</em>
When -3 is raised to an even power, the sign of the product is positive, the same as 3 raised to that power.
