Two hiking paths diverge at an angle of 75. If one person took a path and walked 5 km/h and another person took the other path and walked at 6 km/h, how far apart are they after 12 hours? 4. From a window 20m above the ground, a person could see the top of the house across the street at an angle of elevation of 5 degrees. The angle of depression to the base of the house was 15 degrees. What is the height of the house?
