Mr.Hall stands 200 meters from the base of the water tower. He finds the angle of elevation to the top of the water to be 27 deg

love history [14]

Height of the tower = 101.9 m

Solution:

Given data:

Angle θ = 27°

Adjacent side = 200 m

Opposite side = Height

Let height be taken as h.

The given image shows it is a right triangle.

Using basic trigonometric ratio formulas,

$$\tan \theta=\frac{\text { Opposite side of } \theta}{\text { Adjacent side of } \theta}$

$$\tan27^\circ =\frac{{ h}}{200}$

The value of tan 27° = 0.5095

$$0.5095 =\frac{{ h}}{200}$

Do cross multiplication, we get

0.5095 × 200 = h

101.9 = h

Height of the tower = 101.9 m

7ab a - b
-------------- - --------------
a^2 - b^2 a + b

  7ab a - b
= -------------- - --------------
(a-b)(a+b) a + b

7ab   (a - b)^2
= -------------- - -----------------------
  (a-b)(a+b) (a + b)(a-b)

7ab a^2 - 2ab + b^2
= -------------- - -----------------------
  (a-b)(a+b) (a + b)(a-b)

7ab - a^2 + 2ab - b^2
= -----------------------------------
   (a-b)(a+b)

- a^2 + 9ab -  b^2
= -----------------------------------
   (a-b)(a+b)
