Answer 1

Answer:

Step-by-step explanation:

Trignomentary - real life problem.

We can find the height of the tower without measuring it. WE can find the height  of the tower when we know,

1.  A point which at a distance 'x' from the foot of the tower.

2. The angle of elevation is known  

Eg: A tower stands vertically on the ground. From a point on the ground which is 15 m away from the foot of the tower, the angle of elevation  of the top of the tower is 60°. Find the height of the tower.

AB - tower

We know the adjacent side of 60°  and we have to fing the opposite side of 60°. So, we have to use

$\sf \ Tan \ 60^\circ=\dfrac{Opposite \ side \ of \ 60^\circ}{Adjacent \ side \ of \ 60^\circ}$

$1.732 = \dfrac{AB}{BC}\\\\1.732=\dfrac{AB}{15}\\\\1.732*15=AB$

AB = 25.98 m

Height of the tower ≈ 26 m
