You can use the slope formula to find out how fast object A is moving. It starts off at (0,0) and goes to (2,10). The slope formula is 
. So, you can get the speed by plugging in: 
. Object A is going at 5 meters per second
So the Pythagorean Theorem is a²+b²=c² pretty much all you do is plug in what you know. So for number 3 you would plug in the numbers that you know into the formula.
20²+b²=25²
BD isn't needed in the formula because it's not apart of the legnth we are looking at so you dont need to worry about that.
Now do what the formula says..
400+b²=625
then you would subtract
625-400= 225
and "un-square" the answer by finding the square root
√225 = 15
AB= 15
you can always check your answer
20²+15²=25²
400+225=625
