Answer:

57°

Step-by-step explanation:

Exterior Angle Theorem: An exterior angle of a triangle is equal to the sum of the opposite interior angles.

(9x+16) + (6x+15) = 136

15x + 31 = 136

15x = 105

x = 7

plug into (6x + 15)

6(7) + 15 = 42 + 15 = 57

Solve the equation for [0,2pi]<br> cos2x=1/sqrt2

lapo4ka [179]

$cos(2x) = \frac{1}{\sqrt{2}}$
$cos(2x) = \frac{1}{\sqrt{2}} * \frac{\sqrt{2}}{\sqrt{2}}$
$cos(2x) = \frac{\sqrt{2}}{2}$
$cos(2x) = cos(45)$
$cos(x) = cos(22.5)$
$x = 22.5$

How would you write the following expression as a sum or difference? `"log"(root(3)(2 - x)/(3x))`

pashok25 [27]

<h3>Further explanation</h3>

Let's recall following formula about Exponents and Surds:

$\boxed { \sqrt { x } = x ^ { \frac{1}{2} } }$

$\boxed { (a ^ b) ^ c = a ^ { b . c } }$

$\boxed {a ^ b \div a ^ c = a ^ { b - c } }$

$\boxed {\log a + \log b = \log (a \times b) }$

$\boxed {\log a - \log b = \log (a \div b) }$

<em>Let us tackle the problem!</em>

$\texttt{ }$

$\log \frac{\sqrt{3}(2-x)}{(3x)} = \log \sqrt{3} + \log (2-x) - \log (3x)$

$\log \frac{\sqrt{3}(2-x)}{(3x)} = \log 3^{1/2} + \log (2-x) - (\log 3 + \log x)$

$\log \frac{\sqrt{3}(2-x)}{(3x)} = \frac{1}{2} \log 3 + \log (2-x) - \log 3 - \log x$

$\log \frac{\sqrt{3}(2-x)}{(3x)} = \log (2-x) - \frac{1}{2}\log 3 - \log x$
