Answer:

x=5

y=22

Step-by-step explanation:

By definition a kite is a quadrilateral where contiguous segments are congruent therefore

4x-3 = 2x+7      and    2x = 10    so  x = 5

Remember that the sum of the interior angles of a polygon is equal to 180(n-2)

where n is the number of sides on the polygon. For this case n=4 so we know that

5y+5y+61+79 = 180*2

Therefore

10y +140 = 360

and then

y = 22

Is (-1,2) a solution of y=-5x+7
Arlecino [84]

No, it is not. I will show you:

-1 = x  and 2 = y

2 = -5(-1) + 7

2 is not equal to 12. I hope this is right!

goblinko [34]

Answer:

81

Step-by-step explanation:

let the terms be a,ar,ar²

r=2/3

a+a(2/3)+a(2/3)²=171

multiply by 9

9a+6a+4a=171×9

19 a=171×9

a=(171×9)/(19)

a=9×9=81
