There are ⌊ 999 6 ⌋ − ⌊ 99 6 ⌋ numbers between 100 and 999 (i.e. three digit numbers) which are divisible by six.
It can sometimes be rational
There are 9,000 markers in total
750 x 12 = 9,000
Because it's iscosceles, angle 1 is similar size to the angle on the right leg.
∠1 = 67°
The sum of interior angles in trapezoid equals to 360°.
And because it's iscosceles, the upper angles are in the same size. We can write it as,
the sum of angles = 360°
67° + 67° + ∠2 + ∠2 = 360°
134° + 2 × ∠2 = 360°
2 × ∠2 = 360° - 134°
2 × ∠2 = 226°
∠2 = 113°
Final answer
∠1 = 67°
∠2 = 113°
202 - 18 = 184 (the length is 9ft longer than the width, and you double the length to find the perimeter, so you double the 9)
184 ÷ 4 = 46 (4 being the 4 sides of the rectangle)
width = 46
length = 46 + 9 = 55
55 x 46 = 2530
Area = 2530ft²
