Convert the following angles into degrees and decimal of degree:24°42` and 78°15`?

To convert the angles into degrees and decimal of degree, we need to convert the minutes into degrees by dividing by 60 and then add it to the original degrees.

For 24°42`:
24° + (42/60)° = 24° + 0.7° = 24.7°

For 78°15`:
78° + (15/60)° = 78° + 0.25° = 78.25°

Therefore, the angles in degrees and decimal of degree are:
24°42` = 24.7°
78°15` = 78.25°
