First, calculate 18% of 23.
23 x 0.18 = 4.14
Then, add this value (the increase) to the original value of 23.
23 + 4.14 = 27.14
Rounding off, we get 27.
Ok anddddddddddddddddddddd
Given:
The figure of a pentagon.
To find:
The value of the x.
Solution:
We know that, the sum of all interior angles of a pentagon is 540 degrees. So,



Subtract both sides by 12.


Divide both sides by 33.


Therefore, the value of the x is 16.
Multiply the number of pencils by the length to get total centimeters first, then convert to meters:
24 x 19 = 456 cams.
1 meter = 100 cm
Divide total cm by 100 to get meters
456 / 100 = 4.56 meters
