Answer:

3. isosceles, acute

5. scalene, obtuse

Step-by-step explanation:

3. Two (and only two) sides are the same length (and their opposite angles are the same measure), so the triangle is isosceles. All angles are less than 90°, so the triangle is acute.

5. All angles have different measures, so the triangle is scalene. The largest angle is greater than 90°, so the triangle is obtuse.

Answer:

$a_n=6\cdot (-1)^n$

Step-by-step explanation:

<u>Alternating Sequences</u>

A sequence whose terms alternate in the sign is called an alternating sequence.

The given sequence consists of the numbers -6 and 6 in infinite alternation.

Such sequences can be expressed as equations of the form

$a_n=a\cdot (-1)^m$

Where a is the constant absolute value of each term and m is an expression adequately arranged to reproduce the alternation of signs.

Since the sign is minus for odd terms, and plus for even terms, m=n is a good expression for m. Thus:

$a_n=6\cdot (-1)^n$
