b) 218.5°
c) 218.25°
d) 256.75°

Answer 1

To convert the angle from minutes to degrees, divide the number of minutes by 60. Add the resulting value to the angle given in degrees to find the final angle.

Step-by-step explanation:

To convert the angle from minutes to degrees, we need to divide the number of minutes by 60. In this case, we have 19 minutes, so 19/60 = 0.3167 degrees. To find the final angle, we add this to the angle given in degrees, which is 237.5 degrees. So the final angle is 237.5 + 0.3167 = 237.8167 degrees.
