The ratios of sin x° and cos y° are 15/8.
We have given that,
Use the image below to answer the following question.
We have to determine to find the value of sin x° and cos y°.
By applying Pythagoras theorem in the triangle given in the picture,
<h3>What is
the Pythagoras theorem?</h3>
(Hypotenuse)² = (leg 1)² + (leg 2)²
PO² = (15)² + 8²
PO² = 225 + 64
PO = √289
PO = 17
By applying the sine rule in the given triangle,
sin(x°) = Opposie side/hypotenous
= 15/17
cos(y°) = Adjucent side/hypotenous
= 8/17
The relation between the ratio of sin(x) and cos(x) will be,
![\frac{sinx}{cosx} =\frac{\frac{15}{17} }{\frac{8}{17} }](https://tex.z-dn.net/?f=%5Cfrac%7Bsinx%7D%7Bcosx%7D%20%3D%5Cfrac%7B%5Cfrac%7B15%7D%7B17%7D%20%7D%7B%5Cfrac%7B8%7D%7B17%7D%20%7D)
![=\frac{15}{8}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B15%7D%7B8%7D)
Therefore the ratios of sin x° and cos y° are 15/8.
