50 POINTS!!!!! PLEASE WILL MARK BRAINLIEST
kirill [66]

Answer:

  • Q11 - 12 sides
  • Q12 - 10 sides

Step-by-step explanation:

<u>Use the formula for sum of interior angles of a regular polygon:</u>

  • S = 180(n - 2)

<u>Each angle A measures:</u>

  • S/n = 180(n - 2)/n
  • A = 180(n - 2)n
  • An = 180n - 360
  • (180 - A)n = 360
  • n = 360/(180 - A)
<h3>Question 11</h3>

<u>Each angle is 150, then finding n:</u>

  • n = 360/(180 - 150)
  • n = 360/30
  • n = 12
<h3>Question 12</h3>

<u>Each angle is 144, find n:</u>

  • n = 360/(180 - 144)
  • n = 360/36
  • n = 10

Find the value of each variable
kondaur [170]

Answer:

The correct answer is option C

a = 10√3, b = 5√3, c = 15 and d = 5

Step-by-step explanation:

Points to remember

The angles of a right angled triangle, 30°, 60° and 90° then sides are in the ratio, 1: √3 : 2

<u>To find the value of variables</u>

From the figure we can see 2 right angled triangle with angle 30, 60 and 90

we get, d= 5 then b = 5√3

b = 5√3  the c = 5√3 * √3 = 15

and a = 2 * 5√3 = 10√3

Therefore the correct answer is option C

a = 10√3, b = 5√3, c = 15 and d = 5

Answer:

15). is done

16).

slope =  \frac{ {y}^{1} -  {y}^{o}  }{ {x}^{1}  -  {x}^{o} }  \\  =  \frac{2 - ( - 2)}{ - 3 - 9}  \\  =  \frac{4}{ - 12}  \\ slope =  -  \frac{1}{3}
