5 0

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°

Is 30/12 and 40/16 equivalent?
Flura [38]
30/12 in simplest form is 5/2 (cause 6 * 5 = 30 and 6 * 2 = 12)
40/16 in simplest form is 5/2 (cause 8 * 2 = 16 and 8 * 5 =40)
so yes they're equivalent;
30/12 = 40/16
Hope that helps :D have a nice day!

Compare the functions below: Which function has the smallest minimum?
anzhelika [568]

Answer:

D. All three functions have the same minimum value

Step-by-step explanation:

f(x) = -3 sin (x-pi) +2

Sin has a minimum value of -1, but since it is multiplied by a negative, we want its maximum value

sin has a maximum of 1

f (min) = -3(1) +2 = -1

g(x) has a minimum at x =3  

g(minimum) = -1

h(x) = (x+7)^2 -1

        The smallest a squared value can be is zero

     = 0 -1

h(min) =-1
