Question

value of tan 45°
value of tan 30°
value of sin 90°
value of sin 45°​

Answer 1

□value of tan 45°=1

□value of tan 30°

$\sqrt{3}$

□value of sin 90°=1

□value of sin 45°

$\frac{1}{ \sqrt{2} }$

□tan 45°

$\frac{sin45}{cos45} = \frac{ \frac{1}{ \sqrt{2} } }{ \frac{1}{ \sqrt{2} } } = 1$

□tan 30°

$\frac{sin30}{cos30} = \frac{ \frac{1}{2} }{ \frac{ \sqrt{3} }{2} } = \sqrt{3}$

Answer 2

Answer:

$\tan(45) = 1$

$\tan(30) = \frac{1}{ \sqrt{3} }$

$\sin(90) = 1$

$\sin(45) = \frac{1}{ \sqrt{2} }$
