A student stands 29 m away from the foot of a tree and observes that the angle of elevation of the top of the tree,
measured from a LEVEL 1.5m above the ground, is 38°28'. Calculate the height of the tree to the nearest meter
~~~~~~~~~~~~~~
First, I edited the text to make it harmonious.
Overwise, an unnecessary questions may arise about the table . . . (which is, actually, irrelevant to the problem).
Second, I re-calculated everything and found out that the answer by @mananth is INCORRECT due to incorrect rounding.
I present the corrected calculations below.
tan 38 deg 28' = x/29
x = tan 38deg 28' * 29 =
= 0.794485554 * 29 =
x= 23.04008 m
height of the tree = 23.04008 + 1.5 = 24.504008 m = 25 m (rounded as requested). ANSWER
Solved (correctly).
