A pie chart represents data in a circular form, and the sum of all the angles in the chart always equals 360°.
Each slice of the pie chart corresponds to a portion of the total, and their angles add up to 360°.
Perimeter of Rhombus = 2 (l +b)
= 2 ( 6 +6 )
= 2 (12)
= 24
A polygon having 8 sides is called octagon.
A polygon having 10 sides is called decagon.
A polygon having 4 sides is called quadrilateral.
One nautical mile per hour is equal to 1 knot.
One nautical mile is equal to 6,076 feet (1,852 meters/kilometers).
When a square is rotated by 90 degrees, it still remains a square.
The shape of the square does not change because it has equal sides and 90-degree angles, regardless of its orientation.
The mean of 100 items is 30, so the total sum of all items is:
30 x 100 = 3000
However, two items were wrongly taken as 32 and 12 instead of 23 and 11, which means the correct total sum should be:
3000 - 32 - 12 + 23 + 11 = 2990
Since there are 100 items, the correct mean is:
2990 ÷ 100 = 29.9
So, the correct answer is: 29.9
Let smallest angle = x
Then largest angle = 2 x − 24°
But x + 2 x − 24° = 180°
⇒3 x − 24° = 180°
⇒3 x = 180° + 24 = 204°
⇒x = 204/3 = 68°
∴ largest angle = 180 − 68° = 112°
A protractor allows you to measure and draw exact angles like 72° directly.
A compass alone cannot construct 72° easily without complex geometric steps, so it’s not practical for this angle.
