Answer:

And if we convert to megahertz we got:

Step-by-step explanation:
For any mechanical wave we have the following general relationship:

where:
v represent the speed of the wave = 299790000 m/s
represent the wavelength for the radio station
f represent the frequency of interest
If we solve for the frequency we got:

And replacing the values we got:

And if we convert to megahertz we got:

Answer:
C. 61 degrees
Step-by-step explanation:
a line is 180 degrees
so e and 119 degrees makes a line
so you subtract 180-119= 61 degrees
