If tan @ = then what is sin ?

tanθ = opp/adj

sinθ = opp/hyp

cosθ = adj/hyp

Hope this helps! ;)

if you was gonna solve for a, a is a   < -12

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
