For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
No, it is not. To be correct, the expression requires parenthesis, which are missing.
Yes, sine, cosine, tangent definitions are based on right triangles
That is the correct spelling of "tangent" (intersecting at one point, or sine divided by cosine, or opposite side over adjacent side).

Trig identity... sin/cos = tangent

The tangent of an angle theta is defined as sine(theta) divided by cosine(theta). Since the sine and cosine are Y and X on the unit circle, then tangent(theta) is Y divided by X. The tangent of a function at a point is the line going through that point which has slope equal to the first deriviative of the function at that point.
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
The tangent function is equal to the sine divided by the cosine. In quadrant III, both sin and cos are negative - and a negative divided by another negative is positive. Thus it follows that the tangent is positive in QIII.

Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
Yes, except at odd multiples of pi/2 radians, where the cosine is zero so that the division is not defined.
