6 0

$y = \frac{\sqrt{\left( 1 - \cos (x\,\text{Rationalize}(0.0523599))\right) }}{\sqrt{\left( 1+\sin (x\,\text{Rationalize}(0.0698132))\right) }}$

Answer:

x = 60

Step-by-step explanation:

Combine like terms on the left side of the equation: 2x + x = 3x; -1 + 1 = 0 so the total for the left side is just 3x. Now compare it to the full equation that you have left now, 3x = 180 now do 180/3 = 60

Hope this helps!

Answer:

ADB and ABC are similar

x = 8

Step-by-step explanation:

hypotenuse in ADB = $\sqrt{4^2 + 2^2 } = \sqrt{20}$

since two triangles are similar,

$\frac{2+x}{\sqrt{20} } = \frac{\sqrt{20}}{2}$

solving for x, x=8
