Question

What are the ratios for sin A and cos A? The diagram is not drawn to scale.

Answer 1

sinA=15/17 and cosA=8/17

Explanation:

sine is opposite side over hypotenuse and cosine is adjacent side over hypotenuse

Answer 2

sin A =
`\frac{15} {17}` and cos A =
`(8)/(17)`

Explanation:

We are given a right angled triangle and we are to determine the ratios for sin A and cos A.

Sin is the ratio of perpendicular/hypotenuse while cos is the ratio of base/hypotenuse.

With respect to angle A, base = 8, perpendicular = 15 and hypotenuse = 17.

Therefore,
`sin A = (15)/(17)` and
`cos A = (8)/(17)`.
