Answer:

34°

Step-by-step explanation:

Angles on a straight line add up to 180°.

Therefore, we equate the sum of all angles along the straight line to 180° to solve x:

$x\textdegree+(x+12)\textdegree+100\textdegree=180\textdegree\\\\2x\textdegree=(180-100-12)\textdegree\\\\2x=68\textdegree\\\\x=34\textdegree$

Hence x is 34°

A turtle population grows in a manner that closely resembles a geometric sequence. Given the table of values, determine the turt

AleksandrR [38]

The turtle population will be 486 after 5 years.

<u>Step-by-step explanation</u>:

The general form of a geometric progression or geometric sequence is a, ar, ar², ar³ and so on.

where,

a = first term
r = common ratio

<u>The formula to find the nth term in GP is :</u>

nth term = $ar^{n-1}$

The given sequence 6,18,54.

In this sequence,

The first term, a = 6
The common ratio, r = 18/6 = 3

5th term = $6\times3^{5-1}$

⇒ $6\times3^{4}$

⇒ 6 $\times$ 81

⇒ 486

Therefore, after 5 years the population will be 486.
