Ed is on a road trip. He has already traveled 222 miles and is driving at a rate of 61 miles per hour. Which equation could be used to find how many hours, x, Ed has left in his road trip if he is traveling 619 total miles? A. 61x + 222 = 619

B.
61x + 619 = 222

C.
222x + 61 = 619

D.
222x + 619 = 61

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
