Question

If 2 sin x°-1 = 0 and xº is an acute angle; find: (i) sin xº (ii) xº (iii) cos xº and tan xº.​

Answer 1

$\sf \orange{Answer }$

$\sf \blue{1)}2 \: sin° - 1 \: = \: 0 \:$

$\sf \: sin \: x° = \frac{1}{2}$

$\sf \purple{2)} \: sin \: x° \: = \frac{1}{2}$

$\sf \: sin \: x° =sin \: 30°$

$\sf \: x° = \: 30°$

$\sf \red{3)} \: cos \: x° = \: cos \: 30° \: = \: ( \sqrt{3} )$

$\sf \: tax \: x° \: = \: tan \: 30° \: = \: \frac{1}{ \sqrt{3} }$
