There are 45 numbers between 49 and 95
Numbers in the fifties: 50,51,52,53,54,55,56,57,58,59
Numbers in the sixties: 60,61,62,63,64,65,66,67,68,69
Numbers in their seventies: 70,71,72,73,74,75,76,77,78,79
Numbers in their eighties: 80,81,82,83,84,85,86,87,88,89
Numbers in their nineties: 90,91,92,93,94
Multiples of 2:
50,52,54,56,58,60,62,64,66,68,70,72,74,76,78,80,82,84,86,88,90,92,94
Multiples of 3:
51,54,57,60,63,66,69,72,75,78,81,84,87,90
Multiples of 9:
54,63,72,81,90
Notice that all multiples of nine are also multiples of three? That is because three is a factor of nine
Answer:
∠ KLM = 27°
Step-by-step explanation:
∠ KLM + ∠ NLM = 90 , that is
3x + 7x = 90
10x = 90 ( divide both sides by 10 )
x = 9
Thus
∠ KLM = 3x = 3 × 9 = 27°
Answer: the polygon has 20 sides.
Step-by-step explanation:
The formula for determining the sum of the measure of the interior angles in a regular polygon is expressed as (n - 2) × 180.
if the sum of the measures of the interior angles is 3960
degrees. This means that
(n - 2) × 180 = 3960
Expanding the brackets by applying the distributive property, it becomes
180n - 360 = 3960
180n = 3960 - 360
180n = 3600
Dividing both sides by 180, it becomes
n = 3600/180
n = 20
