Given only the measure of an angle, use a scientific calculator or a book of mathematical tables (if you can find one!).
There are infinite series but they are not particularly easy to work with.
The tangent-tangent angle is formed by two tangents drawn from a point outside a circle to points on the circle. To find the measure of the tangent-tangent angle, you take half the difference of the intercepted arcs. In this case, the arcs measure 135 degrees and 225 degrees. Therefore, the measure of the tangent-tangent angle is (\frac{1}{2} (225^\circ - 135^\circ) = \frac{1}{2} (90^\circ) = 45^\circ).
196-164/2= 16
The measure of the intercepted arc is twice the measure of the tangent chord's angle. Therefore, if the measure of the tangent chord is 74 degrees, the measure of the intercepted arc would be 2 × 74 degrees, which equals 148 degrees.
To find the angle whose tangent is 7.5, you can use the inverse tangent function (arctan). Calculating this, you get ( \theta = \tan^{-1}(7.5) ), which is approximately 82.8 degrees when rounded to the nearest tenth.

to find the measure of an angle. EX: if sin A = 0.1234, then inv sin (0.1234) will give you the measure of angle A
You find the tangent to the curve at the point of interest and then find the slope of the tangent.
A tangent refers to the way in which a curve is measured. The amount of deviation from the segment line is measures, then a formula applied to find the tangent.
