Divide the nonagon radially into 9 congruent, equilateral isosceles triangle. Each triangle has vertex angle of 360°/9 = 40°.
Interior angle of polygon = 180°-40° = 140°.
Sum of interior angles = 9(140°) = 1260°

<h3><u>Explanation :- </u></h3>
• Amount received by Rui = 5x = 5 x 11 = $55..
• Amount received by Vishal = 9x = 9 x 11 = $99..
Let the amount received by Rui be 5x..
Then the amount received by Vishal is 9x ..
And by this data = 5x + 44 = 9x ..
• Amount received by Rui = 5x = 5 x 11 = $55..
• Amount received by Vishal = 9x = 9 x 11 = $99..
<h3>Hope this helps you..! </h3>

Answer:
-2/3
Step-by-step explanation:
To find the slope we use the formula
m= ( y2-y1)/(x2-x1)
= ( 14-10)/(-18- -12)
= (14-10)/(-18+12)
= 4/-6
= -2/3
