Pythagoras Theorem: $\large a^2 + b^2 = c^2$  or   $\large c = \sqrt{a^2 + b^2}$ 
where c is the hypotenuse (that is, the side opposite to the 90 degrees angle.)

aum · Answer

Here, a = 40,  b = 25.  Plug it into $\large c = \sqrt{a^2 + b^2}$   and calculate c.

Okay thnak you so much do i do the equation for these problems also ?

Yes, for all the above problems you use the Pythagoras formula a^2 + b^2 = c^2.
But you should first identify the hypotenuse in each of those triangles.
The hypotenuse is the side opposite to the right angle or the 90 degree angle. 
The length of the hypotenuse is "c".  
The others two sides are a and b and it does not matter which side is 'a' and 'b'.  
But the hypotenuse should always be 'c' in the above formula.
