Question

What is the value of sin120

Answer 1

Answer:

$<marquee scrollamount=10>pls follow me and mark as brainliest$

Step-by-step explanation:

$\sf\red{sin120°} \\ \sf\purple{ = > sin(1 \times 90 ° + 30°)} \\ \sf\blue{ = > cos30° } \\ \sf\orange{ = > \frac{ \sqrt{3} }{2} }$

$\large\boxed{ \fcolorbox{red}{blue}{pls \: follow \: me}}$

$\large\boxed{ \fcolorbox{orange}{yellow}{mark \: as \: brainlist}}$

$\sf\red{sin0 ° = 0} \\ \sf\red{cos0 ° = 1} \\ \sf\red{tan0 ° = 0} \\ \sf\purple{sin30 ° = \frac{1}{2} }\\ \sf\purple{cos30 ° = \frac{ \sqrt{3} }{2} } \\ \sf\purple{tan30 ° = \frac{1}{ \sqrt{3} } } \\ \sf\blue{sin45 ° = \frac{1}{ \sqrt{2} } } \\ \sf\blue{cos45 ° = \frac{1}{ \sqrt{2} } } \\ \sf\blue{tan45 ° = 1} \\ \sf\orange{sin60 ° = \frac{ \sqrt{3} }{2} } \\ \sf\orange{cos60 ° = \frac{1}{2} } \\ \sf\orange{tan60 ° = \sqrt{3} } \\ \sf\pink{sin90 ° = 1 } \\ \pink{cos90 ° = 0} \\ \pink{ tan90 ° = \infty }$

Answer 2

Step-by-step explanation:

HELLO DEAR☺️

Sin120

=sin(180-60)

=sin60

=√3/2
