Answer:
<em> = n² + 4n ; n = 11 </em>
Step-by-step explanation:
= 
[2 
+ (n - 1)d]
~~~~~~~~~
= 5
d = 7 - 5 = 2
= [ 2(5) + 2(n - 1)] = ( 8 + 2n ) = 4n + n²
<em> = n² + 4n</em>
n² + 4n = 165
n² + 4n - 165 = 0
(n + 15)(n - 11) = 0 ( n ≥ 0 ) ⇒ <em>n = 11</em>
If my memory serves me well, according to charles law, use this formula: <span>m=(<span><span><span>P2</span>−<span>P1)/(</span></span><span><span>T2</span>−<span>T1). This is A.
In this cotext, slope is the constant.

180=51+2x+3+4x+8
180=51+11+6x
180=62+6x
-62 -62
-----------
118=6x
---------
6x 6x
x=17
exterior angle = 4x+8
4(17) + 8
68 + 8
76
1). The 2 angles add up to 180 degrees.
2). And 3). The 2 angles are equal.
