Answer:

84°
125°

Step-by-step explanation:

<u>Sum of the interior angles of a regular polygon:</u>

S(n) = 180°(n - 2), where n- number of sides

<h3>Exercise 4</h3>

<u>Pentagon has sum of angles:</u>

S(5) = 180°(5 - 2) = 540°

<u>Sum the given angles and find x:</u>

x° + 122° + 100° + 90° + 144° = 540°
x° + 456° = 540°
x° = 540° - 456°
x° = 84°

<h3>Exercise 5</h3>

<u>Hexagon has sum of angles:</u>

S(6) = 180°(6 - 2) = 720°

<u>Sum the given angles and find x:</u>

x° + 110° + 160° + 105° + 105° + 115° = 720°
x° + 595° = 720°
x° = 720° - 595°
x° = 125°

Question part points submissions used consider the following. g(x)={((x**2-a**2)/(x-a) text(if ) x != a,4 text(if ) x =

EastWind [94]

For $x\neq a$ , we have

$\dfrac{x^2-a^2}{x-a}=\dfrac{(x-a)(x+a)}{x-a}=x+a$

So for $g(x)$ to be continuous at $x=a$ , we require that the limit as $x\to a$ is equal to 4.

$\displaystyle\lim_{x\to a}g(x)=\lim_{x\to a}(x+a)=2a=4\implies a=2$
