( Z = √(60² + 60²) ). So if you enter that into your scientific calculator you will receive an answer of 84. 85Ω. ( Z = 84. 85Ω )

You should have an equation that looks like this: (60/60 = 1)

This can also be expressed as a percentage therefore you multiply 0. 71 by 100 giving you a power factor of 71%. [9] X Research source
