A rational number is part of a whole expressed as a fraction, decimal or a percentage. ... Alternatively, an irrational number is any number that is not rational. It is a number that cannot be written as a ratio of two integers (or cannot be expressed as a fraction).
First, we work out the final angle of the left triangle, which has a total of 180°. To do this we take 40° and 66° from 180°, giving us <u>72°</u>
Because there is a straight line along the bottom (which will total 180°), we take both 72° and 56° from 180°, giving us <u>52°</u>, which is the bottom left angle of the right triangle.
Finally, to work out '?', we take 52° and 40° from 180° to get our final answer of <u>88°.</u>
Hello there. The sequence is being divided by ten 51/10= 5.1 5.1/10 = 0.51 0.51/10 = 0.051, and so on. You can also reverse the following sequence and multiply it by ten.
