Answer:b=5
Step-by-step explanation:the formular for pythagoras theory is
C^2=a^2+b^2
13^2=12^2+b^2
169=144+b^2
Collect like terms
169-144=b^2
b^2=25
Take the the square root of both sides
b=square root of 25
b=5
Multiply them back into each other... You would multiply your answer with the number you divided by (the number ouside the table if you used the table... ) and you should get the larger number you divided.
1 purse and 1 watch is 27€
2 purse and 1 watch is 41€
So we can see the watch is constant means 1 watch is every time but purse is increase by 1 in the next expression
So 41-27 = 14€ is one purse
because the watch is every time one, so the next value increase is by purse
1purse and 1watch = 27
We know,
1 purse is 14€
So 27-14=13€ is one watch
We can check by
1 purse is 14 so two purse is 14*2=28
28+13=41
Which is same as they said in second expression
