Question

Tan theta =2x(x+1)/2x+1 then find sin theta

Answer 1

SOLUTION

Assuming the question is,

$= > tan \theta = \frac{2x(x + 1)}{2x + 1} = \frac{perpendicular}{base} \\ = > {h}^{2} = {p}^{2} + {b}^{2} (by \: pythagoras \: theorem) \\ \\ = > {h}^{2} = {2x(x + 1)}^{2} + {2x + 1}^{2} \\ \\ = > h = \sqrt{2x(x + 1</em></strong><strong><em>)</em></strong><strong><em> {}^{2} + 2x + 1 {}^{2} }$
