  • 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?
