A long horizontal wire carries 26.0 A of current due north. The Earth's field 21.0 cm due west of the wire points north but downward, 43 degrees below the horizontal, and has magnitude of 5.0×10−5 T.

What is the magnitude of the net magnetic field 21.0 cm due west of the wire?

What is the angle below the horizontal of the net magnetic field 21.0 cm due west of the wire?
