Have you not paid your 9th grade mathematical instructor attention? Verybad
So I know my hair is 20 meters long, and the elevation angle here seems like 30 degrees. So here's the question, How long should the tower be?
C
A
B
Hmm , Therefore the length of the tower is 10m long
So AB = The lenght of the tower AC = The length of may hair Angle C = Angle of elevation = 30 degrees
SIN = 30 Opp / hyp 1/2 = Ab / AcAB= 20/ 2= 10 m
In this example, how much do you believe is the depression angle?
Now, given the same measurements that we discovered previously, it is essential to use the same reasoning to see how far the foot of the tower will be when you are down
TAN 60 = Opp /Hyp*3 = A/BC8=10/BCBC = 10*3
AB = length of the tower Angle A = angle of depression = 60 Degrees BC = Distance betweenyou and the foot of the tower
