Question

Find the distance between a and b.
a = −60, b = 70

Answer 1

distance between a and b = 92.2

Explanation:

let the distance between a and b is the hypotenuse, h and

a and b are the legs of the right angled triangle,

h² = a² + b²

h² = (-60)² + (70)²

h² = 3600 + 4900

h² = 8500

h = √8500 = 92.2

distance between a and b = 92.2

Answer 2

distance is 130

Explanation:

-60 + 60 is 0.

then, 0 to 70 is 70

so 60 +70=130
