Question

Point A lies on the circle and has an x-coordinate of 1.

Which is the correct calculation of the y-coordinate of point A?

Answer 1

d

Explanation:

u do the thing and u do it right and somehow it equals 2 (edge 2022)

Answer 2

y=0

correct way to solve it is y= xtan(theta)

Explanation:

You did not mention if it is trigonometry but we assume that it is.

In trigonometry, a point with x-coordinate = 1 at a circle is horizontal line. the angle at this point is 0.

The correct way to solve it is to say tan = opposite/adjacent

since the angle is zero, and adjacent side x=0, tan 0=opposite/1

opposite (y) = 1 tan 0

y = 1*0 =0
