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°

Nataliya [291]

Answer:

2.5 inches

Step-by-step explanation:

1 feet = 12 inches

The length is 16 ft x 12 = 192 inches

The length was scales by an unknown measure which i would represent with x . The equation is as follows

192 inches x a = 4 feet

a = 48

The kitchen was scaled by 48

10 x 12 = 120 inches

120/48 = 2.5 inches

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed o

kvv77 [185]

The left-handed students
12% are left handed, percent means per hundred. Change percent into per 100.
12% = $\dfrac{12}{100}$

Then simplify the fraction by dividing the numerator and denominator by 4
$\dfrac{12}{100}$
= $\dfrac{12:4}{100:4}$
= $\dfrac{3}{25}$
This is the fraction showing the proportion of the left-handed students

The right-handed students
Determine the fraction showing the proportion of the right-handed students
1 - the left-handed
= 1 - $\dfrac{3}{25}$

Equalize the denominator to 25
$\dfrac{25}{25} - \dfrac{3}{25}$

Simplify
$\dfrac{21}{25}$
This is the proportion of the right-handed students

<span>Are there more right-handed or left-handed students?
There are more right-handed students than the left-handed students, because 21/25 is more than 3/25</span>
