If theta is an angle in standard position and its terminal side passes through the point (-20;21), find the exact value of sin theta in simplest radical form.​

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

sorry not knowing about that

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
