1+cos2A/cos2A = tan2A/tanA prove LHS=RHS

son4ous [18]

$RTP: \frac{1 + cos(2A)}{cos(2A)} = \frac{tan(2A)}{tan(A)}$

$LHS = \frac{1 + cos(2A)}{cos(2A)}$
$= \frac{1 + \frac{1 - tan^{2}(A)}{1 + tan^{2}(A)}}{\frac{1 - tan^{2}(A)}{1 + tan^{2}(A)}}$
$= \frac{\frac{1 + tan^{2}(A) + 1 - tan^{2}(A)}{1 + tan^{2}(A)}}{\frac{1 - tan^{2}(A)}{1 + tan^{2}(A)}}$
$= \frac{2}{1 - tan^{2}(A)}$
$= \frac{2}{1 - tan^{2}(A)} \cdot \frac{tan(A)}{tan(A)}$
$= \frac{\frac{2tan(A)}{1 - tan^{2}(A)}}{tan(A)}$
$= \frac{tan(2A)}{tan(A)}$
$= RHS$ , as required.

Building A is 480 feet tall and building B is 654 feet tall. If the angle of depression form the top of building b to the top of

ahrayia [7]

Answer:

129.3 feets

Step-by-step explanation:

Using the solution diagram attached below :

The difference in height of the two buildings :

Building B - Building A = (654 - 480) = 174 feets

Using trigonometry :

Cosθ = opposite / Adjacent

Cos 42 = d / 174

d = 174 * Cos 42

d = 129.307

d = 129.3 feets
