The solution rounded to the nearest integer is (-2,6)
60 flowers.
15 tables have 1 flower. 1X15=15
If 15 out of 24 have 1, that means 9 have 5. 9X5=45. 15+45=60
Answer:
n = 9
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Given 3 angles and the remaining angle of 141° then there are
141(n - 3) angles of this size
Then
99 + 153 + 162 + 141(n - 3) = 180(n - 2) , that is
414 + 141n - 423 = 180n - 360
141n - 9 = 180n - 360 ( subtract 141n from both sides )
- 9 = 39n - 360 ( add 360 to both sides )
351 = 39n ( divide both sides by 39 )
9 = n
The polygon has 9 sides
So first to find the area do 8 times 3/4 and that will give u the area.
33 rounded to the nearest 10 is 30, 89 rounded to the nearest 10 is 90. So 90+30 is 120. Let me know if I am right!
