By trigonometric solution of triangles we conclude that the actor is staying at the balcony of the second floor.
In which floor of the hotel does an actor stay in a balcony?
This problem presents an application of trigonometric resolution of triangles to find the floor where the actor is in terms of the height of the building. Based on the picture seen in the image, we find that all known dimensions of the triangle , three angles and a side, are:
A = 140°, B = 30°, C = 10°, p = 6 m
First, we must find the length of side AP by law of sines:
b / sin 30° = 6 / sin 10°
b = 6 × sin 30° / sin 10°
b ≈ 17.276 m
Second, the height of the building is found by trigonometric functions:
h = (17.276 m) · sin 40°
h ≈ 11.105 m
Therefore, the floor where the actor stays is:
3.8 + 3 · n = 11.105
3 · n = 7.305
n = 2.435
n = 2
By trigonometric solution of triangles we conclude that the actor is staying at the balcony of the second floor.
