Adiagonal of a parallelogram is 50 inches long and makes angles of 37°10' and 49°20' with the sides. solve for the longest side of the parallelogram.

first off, did i do this right and secondly, what do 37°10' & 49°20' mean?

Check the picture below

make sure your calculator is in Degree mode, since the angles are in degree
and pretty sure your calculator will have a [° ' "] button to enter degrees and minutes and seconds

if not, you can just convert 49°20' to simply 148/3 degrees, and use that then

The answer is that the rate of change is $50 per 1 monthhope this ; )
