xz_007 [3.2K]

Answer:

14.40646471 =x

Step-by-step explanation:

tan (42) = x/16

Multiply each side by 16

16 tan 42 = x/16 *16

16 tan 42 = x

16 * .900404044 = x

14.40646471 =x

Please can someone prove this equation

zubka84 [21]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

sin²x + cos²x = 1

Consider the left side

2cos²A - 1 ← replace 1 by sin²A + cos²A

= 2cos²A - ( sin²A + cos²A)

= 2cos²A - sin²A - cos²A

= cos²A - sin²A = right side ⇒ verified

RoseWind [281]

Answer:

The first option is the correct option

Step-by-step explanation:

From the question the slope AC is evaluated as

$m_1 = \frac{b-0}{a- (-c)}$

$m_1 = \frac{b}{a+c}$

And the slope of line CB is mathematically evaluated as

$m_2 = \frac{0-b}{c-a}$

$m_2 = \frac{b}{c-a}$

Now for lines that are perpendicular to each other then the product of their slope should be equal to -1

So if $m ZC$ $= 90^o$

Then

$m_ *m_2 = -1$

i,e

$[\frac{b}{a+ c} ] [\frac{b}{a-c} ] = -1$
