What is the distance between - 7,-5 and 2,3?

For this we will use pythagoras theorem to find the distance

we need to find the first two sides by finding the distance between the corresponding sides

for - 7 and 2 the difference is 9 and for - 5 and 3 the distance is 8

pythagoras thereom is a^2+b^2=c^2

so 9^2+8^2=x^2

81+64=x^2

145=x^2

x=12.04159 ...

x=12.042 (3dp)
