Along a long, straight stretch of mountain road with a 7.2 % grade, you see a tall tree standing perfectly plumb alongside the road. From a point 450 feet downhill from the tree, the angle of inclination from the road to the top of the tree is 6.2 degrees. Use the Law of Sines to find the height of the tree to the nearest tenth of a foot.

Naruto is choosing between two venues that will deliver food to his house. with probability 1/3 he will choose ramen mania (r), and with probability 2/3 he will choose sushi (s). if he chooses r, 15 minutes after making the call, the remaining time it takes the food to arrive is exponentially distributed with average 10 minutes. if he orders s, 10 minutes after making the call, the time it takes the food to arrive is exponentially distributed with an average of 12 minutes. given that he has already waited 25 minutes after calling, and the food has not arrived, what is the probability that he ordered from r? i am really stuck on how to set this up, so if you could be extra clear, that would be super ! in advance
