Answer:
d. -38
Step-by-step explanation:
Arithmetic sequence concepts:
The general rule of an arithmetic sequence is as follows:

In which d is the common diference between each term.
We can expand the general equation to find the nth term from the first, by the following equation:

In this question:

17th term:

So the correct answer is:
d. -38
The answer is D. The answer is D because when It is simplified 7?49. The answer is the only possible answer could be correct since the rest of their maths don't add up.

Answer:
acute-angled
Step-by-step explanation:
It doesn't have a right angle and one of its corners isn't for than 90 degrees
The distance around the outside a circle is its circumference. Consider the formula for the circumference of a circle, Circumference = Pi x Diameter. Solving for Pi we get, Pi = Circumference divided by Diameter.
The Law of Sines says



We don't have to worry about the obtuse supplement because a triangle can only have one obtuse angle, and that's B.

Answer: A=29.44°, C=34.96°
