To put it simply, irrational numbers are numbers that cannot be expressed as a fraction. In other words, irrational numbers are numbers that cannot be terminated(stop repeating) or continuously repeated as a single repeating number(.666 or .333 for example). So pi is a irrational number since it repeats but with different numbers repeating each time.

Hmm
7
look at perfect squer befre and after
4=2^2
9=3^2
4<7<9
therefor
√4<√7<√9
2<√7<3
between 2 and 3
Its a right angled triangle. You have C and have B all you need to find is A. usually for a question like this you would use the Pythagorean theorem which is A2+B2=C2 but since we already have c we will use C2-B2=A2
Now we fill in the values. (21)2-(9)2=A2
441-81=360^2 so now with the 360^2 we have to squareroot it so the square root of 360 is 18.973f
