We have the <span> Trigonometric Identities : </span>secx = 1/cosx; (sinx)^2 + (cosx)^2 = 1;
Then, 1 / (1-secx) = 1 / ( 1 - 1/cosx) = 1 / [(cosx - 1)/cosx] = cosx /
(cosx - 1 ) ;
Similar, 1 / (1+secx) = cosx / (1 + cosx) ;
cosx / (cosx - 1) + cosx / (1 + cosx) = [cosx(1 + cosx) + cosx (cosx - 1)] / [ (cosx - 1)(cox + 1)] =[cosx( 1 + cosx + cosx - 1 )] / [ (cosx - 1)(cox + 1)] = 2(cosx)^2 / [(cosx)^2 - (sinx)^2] = <span> 2(cosx)^2 / (-1) = - 2(cosx)^2;

Rewrite in logarithmic form 19^2 = 361

Aneli [31]

Answer:

$\log_{19}{361}=2$

Step-by-step explanation:

We know that taking logarithms performs the transformation ...

$b^e=x\\\\e\cdot\log{b}=\log{x}\quad\text{take logs}\\\\e=\dfrac{\log{x}}{\log{b}}\quad\text{divide by $\log{b}$}\\\\\log_b{x}=e\quad\text{use the change of base formula}$

Then for b=19, e=2, x=361, we have

$\boxed{\log_{19}{361}=2}$

PLEASE ANSWER ASAP!

x = 56°

Solution:

Part A:

Given data:

2x and 68° are adjacent angles in a straight line and their measures have sum of 180°.

Part B:

<em>Sum of the adjacent angles in the straight line is 180°.</em>

2x + 68° = 180°

Subtract 68° from 180°, we get

⇒ 2x = 112°

Divide by 2 on both sides, we get

⇒ x = 56°

The value of x is 56°.

Part C:

By part A and part B,

2x° + 68° = 2(56°) + 68°

= 112° + 68°

= 180°

2x° + 68° = 180°

Hence proved.
