The point (8/17,y) lies in the first quadrant of the unit circle. if θ is the angle between the radius joining this point and the positive x-axis, then sin θ= and tan θ= ,

After making the reference triangle, we get the hypotenuse 17, opposite side 15, and adjacent side 8. Then, we can answer the following
sinθ=15/17
tanθ=15/8
