Question

Use the image below to answer the following question. What relationship do the ratios of sin x° and cos y° share? (1 point)
The ratios are opposites ( negative 7 over 25 and 7 over 25 ).
The ratios are reciprocals ( 7 over 25 and '25 over 7 ).
The ratios are both identical ( and 7 over 25 ).
The ratios are both negative ( negative 25 over 7 and negative 25 over 7 ).

Answer 1

Please post the image.

Answer 2

Answer 3

sin x = 7/25

cos y = 7/25

sin /cos = ?

Answer 4

no clue, i missed a huge chunk of school

Answer 5

i need huge help

Answer 6

As @jhonyy9 mentioned, both sin(x) and cos(y) are the same value

This is because
sin(angle) = opposite/hypotenuse
sin(x) = 7/25

and
cos(angle) = adjacent/hypotenuse
cos(y) = 7/25

The opposite side is the leg furthest from the reference angle, while the adjacent side is the closest leg to the reference angle.

For instance, if x was the refence angle then we can see that

which helps us set up the sine ratio mentioned

Answer 7

A useful rule is that
sin(x) = cos(y) if and only if x+y = 90

Similarly,
sin(y) = cos(x) if and only if x+y = 90
