Question

Trigonometry help? :)

If the cos 30° = square root 3 over 2 , then the sin 60° = _____.

Answer 1

@kayders1997 ? ^-^

Answer 2

square root 3 over 2, because the angles are complementary

sin(70)= cos(20)

tan x = sin x / cos x
z/10 = sin x / (10/y)
sin x = (z/10)(10/y) = z over y

Answer 3

I'm not sure I understand... I saw this on yahoo btw lol
How do you get z and y?

Answer 4

I know the answer but I need to be walked through it

Answer 5

Thank you for trying though! :)

Answer 6

@Michele_Laino maybe? c:

Answer 7

@Nnesha is it possible you could help? ^^

Answer 8

sure. do you know the relationship of cos sin and theta ??

Answer 9

\[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\]

Answer 10

use the given informaton
cos 30 degree = sqrt{3}/2
and cos = adjacent over hypotenuse write these values on the right triangle
it's a right triangle so if one angle is 30 what would be the 3rd angle equal to ??
and how would you find 3rd side of right triangle ?any idea :=))
