Talia took the bus from her home to the bank and then walked back to her home along the same route. the round trip took 0.9 hours total. the bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. use the table to complete these statements.

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°

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
