In a right triangle, the two variable angles are always less than 90° (See Interior angles of a triangle). But we can in fact find the tangent of any angle, no matter how large, and also the tangent of negative angles. For more on this see Functions of large and negative angles.
In a right-angled triangle, one angle (straight line) will always be 90 degrees, and the remaining acute, ie, less than 90 degrees each.
Because a right triangle is a triangle with a 90 degree angle, solving a right triangle requires that you find the measures of one or both of the other angles. How you solve will depend on how much information is given.
