You talk to a friend who lives in a different state. she tells you that today it is 12 degrees below zero where she lives. you tell her it is 54 degrees where you live. what is the difference in temperatures?

66

Step-by-step explanation:if its negative you subtract all of the 54 then add -12 to tha

it would be a 66 degrees difference

Step-by-step explanation:

because 54-(-12)=42

or

-12+66=54

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

you can use a^2+ b^2=c^2
