In ΔABC, a = 4 inches, b = 5.8 inches and ∠C=99°. Find ∠B, to the nearest 10th of an degree.

m∠B = 49.4°

Step-by-step explanation:

Use the law of cosines to get side c, and then the law of sines to get angle B

sin C/c = sin B/b

sin 99/7.543 = sin B/5.8

sin B = 5.8 sin 99/7.543

        =  .75945

m∠B = arcsin .75945 = 49.4°

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

nope.   happens to me as well.
