radius or r= 10
Angle and coordinates are in in quadrant 2
sin theta= 3/5

Determine the coordinates.

Answer 1

sin theta= y/r
y= 3 or 6
r= 5 or 10

x= by pythagreom theorem

Answer 2

x= 8


I am wondering if the coordinates are


(-4/5 , 3/5) or ( -8, 6)

Answer 3

Remember the coordinates \(\large (rcos(\theta), rsin(\theta))\)

Answer 4

Oh interesting, so that means the coordinates are (-8 , 6)

Answer 5

Correct indeed :)

Answer 6

Thank you :)

Answer 7

No problem :)
