Select the correct answer. the measure of an angle formed by two secants intersecting inside the circle equals a) 1/2 the sum of the intercepted arcs b) 1/2 the difference of the intercepted arcs c) 1/2 the measure of the intercepted arc

A. 1/2 the sum of the intercepted arcs

A) 1/2 the sum of the intercepted arcs

Step-by-step explanation:

Definition of secant : Secant is a line which intersects a circle in exactly two points.

Also, when two secants intersect inside a circle then the measure of the angle formed is one-half the sum of the measures of the intercepted arcs.

Hence, OPTION A is correct.

Sec  x and cot x are the reciprocals of cos x and tan x  respectively.

So, for example,  cos x = adj / hyp,  so sec x = hyp / adj

The last choice is the correct one  because tan x  = opp / adj  so cot  = adj / opp.
