Question 934006

{{{theta}}} is an angle in Quadrant {{{I}}}
 
 {{{tan^2(theta) - 4 = 0}}}

 {{{tan^2(theta) =4}}}

 {{{tan(theta) =sqrt(4)}}}

 {{{tan(theta) = 2}}} or {{{tan(theta) = -2}}}

since {{{theta}}} is an angle in Quadrant {{{I}}} we will use only {{{tan(theta) = 2}}}

if {{{tan(theta) = 2}}} => {{{theta=63.43}}}°
