Question 333055
in mathematics, there are many ways to solve some problems.
---
 
the domain {{{0<x<90}}} puts you in the first quadrant, where x=positive, y =positive
--
solve for x
{{{2*sin(x) = cos(x)}}}

{{{2 = cos(x)/sin(x)=cot(x)=1/tan(x)}}}  (divide both sides by sin(x)
{{{tan(x)=1/2}}}    (invert both sides of the equation)
{{{x=arctan(1/2)=26.565}}}
since x=26.565 resides within the domain {{{0<x<90}}} this is the answer
