Hi friends...Good morning....I am here with you guys to discuss on trigonometry problems as i promised you earlier. Some problems on trigonometry have already been discussed look into them too.Look for an example of trigonometry problem below.
If the distance of John standing from a wall is 100 m and the angle subtended by the top of the wall with the ground is 30o, measure the height of the wall in meters?
Solution:
* AB = distance of the man from the wall = 100 m
* BC = height of the wall = h (which has to be calculated)
* The trigonometric function that uses AB and BC is tan A , where A = 30o.
So tan 30o = BC / AB = h / 100
Therefore height of the wall h = 100 tan 30o = (100) 1/√3 = 57.74 m.
Lets work on coterminal angles in our next post....Guys practice many more such problems...
