TEA [102]

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°

Find the distance of the line segment joining the two points (-4 /2 - /12) and (/32, 2/3)

astraxan [27]

Answer: $4\sqrt{3}$ .

Step-by-step explanation:

Distance formula : Distance between points (a,b) and (c,d) is given by :-

$D=\sqrt{(d-b)^2+(b-a)^2}$

Distance between points $(-4\sqrt{2},\sqrt{12}) \text{ and }(-\sqrt{32}, 2\sqrt{3})$ .

$D=\sqrt{(2\sqrt{3}-(-\sqrt{12}))^2+(-\sqrt{32}-(-4\sqrt{2}))}\\\\=\sqrt{(2\sqrt{3}+\sqrt{2\times2\times3})^2+(-\sqrt{4\times4\times2}+4\sqrt{2})^2}\\\\=\sqrt{(2\sqrt{3}-\sqrt{2^2\times3})^2+(-\sqrt{4^2\times2}+4\sqrt{2})^2}\\\\=\sqrt{(2\sqrt{3}+2\sqrt{3})^2+(-4\sqrt{2}+4\sqrt{2})^2}\\\\=\sqrt{(4\sqrt{3})^2+0}\\\\=4\sqrt{3}\text{ units}$

Hence, the correct option is $4\sqrt{3}$ .
