Amar and his friends went to a movie at 4:45 p.m. The movie ended at 6:20 p.m. PART A How long was the movie in hours and minute
babunello [35]

Answer:

The movie was 1 hour and 35 minutes long. (Or 95 minutes long)

Step-by-step explanation:

Well let's see:

It will take 15 minutes from the start to reach 5:00 PM

4:45+0:15=5:00

Now it will be 1 hour and 20 minutes from 5:00 PM to reach the end time of the movie.

Adding the minutes and hours together:

1 hour + 20 minutes + 15 minutes = 1 hour and 35 minutes

Solve the triangle for x.
nalin [4]

Answer:

90.4°

Step-by-step explanation:

Use Law of Cosines to solve:

12² = 9² + 8² - 2(9)(8)Cos X

  144 = 81 + 64 - 144Cos X

     -1 = -144Cos X

         -1/144 = Cos X

            Cos^-1 (-1/144) = X

                     X = 90.39789056°
