Divide the number of flowers by 3 and that is how many rows there are
12 / 3 = 4
18 / 3 = 6
21 / 3 = 7
30 / 3 = 10
<span>15 - 13(2x + 6) < 15 - 3(6x - 7)
15 - 26x - 78 < 15 - 18x + 21
-26x -63 < -18x + 36
-8x < 99
x > -99/8
or
x > - 12.375

Answer:
25°
Step-by-step explanation:
the sum of angles in a Δ = 180°
the largest angle = 100°
the second largest angle = x + 30
the third angle = x
100 + (x +30) + x = 180
100 + x + 30 + x = 180
130 + 2x = 180
2x = 180 - 130
2x = 50
x = 50/2 = 25°
the largest angle = 100°
the second largest angle = x + 30 = 25 + 30 = 55°
the third angle = x = 25°
100° + 55° + 25° = 180°
