Trigonometry homework question answer, step 1, image 1

Let AB represents height fire lookout tower ,C be the position of near fire and D be the position of far fire.

∠EAD=∠ADB=1.70      ...(alternate angles)∠EAC=∠ACB=13.90      ...(alternate angles)

AB=3004 ft

d1 is distance of near fire from lookout tower.

d2  is distance of far fire from lookout tower.

d3 is distance of far fire from near fire.
