Chief Grant inspects the scene from 30 feet at an angle of 59 degrees,. He needs to know how high up the fire is to know how to adjust the ladder, so he uses trig. He calculates that tan(59) multiplied by 30 = 49.9 feet high, so the fire was located 49.9 feet high.
As the fire grows larger, he directs the rest of his men to quickly locate the safest entry ways, keeping height in mind. He finds that the safest entry is on the other side of the building, forcing them to reposition the trucks. After repositioning, they find that with the same height and angle, their distance was unknown. As the ladder is angled and 30 feet to the building from the truck, he used cos(59) times 30 to get the distance (a) as 15.5 feet.
After searching and clearing the building, Chief Grant and the others proceed to start evacuating the building. Chief Grant calculates the level of elevation from the safe entrance of the building to the end of the ladder. Using trig, he finds that the angle between the entrance and the top of the ladder. Using inverse sin, he found that the angle was in fact 1.7 degrees.
Shortly after, it was declared that the only damage done was minimal structure damage, and the firefighters went right back to the station, awaiting another moment of selfless bravery to come.
