Two hikers come to a fork in the road, where the paths diverge at an angle of 39 degrees

Hiker A heads down one path at 6.2 km/h, while hiker B moves down the second path at 5.4 km/h.

After travelling for an hour and a half, hiker A shoots up a flare that rises 0.8 km into the air.

With what angle of elevation (to the nearest degree) does the hiker B see the flare when it is

at its highest point? [6]

After 1 1/2 hr hike A has travelled 1 1/2 x 6.2 Hiker B has travelled 1 1/2 x 5.4

Use law of cosines to find the distance between the two hikers at this point

then the tangent of angle in question will be .8 km / (distance between hikers)
