Real life applications of trigonometry
Текст на Статията
- Tell me something new Percy.... anyways what's up?
- Hey Annabeth! I am doomed.
- Birds.
- yeah... which I assume you didn't know about hence you didn't do it
- yeah sure! come with me
- Anyways, Jason told me in the bus that we had to create a real life problem related to trigonometry and solve it for the math project
- Bingo! so all I need is your help in making the question, I will try to solve it.
- B
- C
- 40 m from the base.
- so here's the question: you want to determine the height of that tower. You measure the angle at A and found that tan A= 3/4.
- A
- ok.... so I need to find the height of the tower if A is some m from the base right
- So here BC represents height of the tower, AB represents the distance between the tower from the point of observationnow we need to find the height of the tower(BC)tanA= opposite side/ adjacent sidetanA = BC/AB
- Given: tanA = 3/43/4 = BC/403 * 40 = BC * 40BC = (3 * 40)/4BC = (3 * 10)BC = 30 mThe height of the tower is 30 m
- Depends on how you attend the question....anyways let's go now, break time is almost over
- Was math always this easy or am I wrong?
