Given cos theta = -2/3 and angle theta is in Quadrant III, what is the exact value of sin theta in simplest form? Simplify all radicals if needed.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
