This summer, the harris family wants to go to san diego, california. they estimate that their destination is about 658 miles from their house. if they drive 75 miles each hour and and they add another 34 miles to the the total distance to sightsee, about how long should it take them to get to their destination?

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

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
