Answer:

A = 60 and B = 30

Now, A + B = 60 + 30 = 90

Also, A – B = 60 – 30 = 30

sin (A + B) = sin 90 = 1

sin A cos B + cos A sin B = sin 60 cos 30 + cos 60 sin 30

amid [387]

Answer:

Your answer is 37

Step-by-step explanation:

Caanan is 62 miles away and since he drives at 50 miles per hour, and if it is 2:30 then 30 minutes is half a hour, which means you divide 50 in half by 2 and get 25. After you do that then you subtract 62 and 25 to get your answer 37. Have a good day!!! :)
