Suppose sin (A) =2/5. Use the trig identity sin ^2 (A) + cos^2(A) =1 and the trig identity tan (A) = sin(A)/cos (A) find tan (A) in quadrant 1

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.

we know that

major arc is defined as the bigger arc connecting two points on the edge of a circle. measure of major arc is always more than ° or π radian

in this problem

the mayor arc is bac

find the ratio of the measure of the major arc to the measure of the minor arc

therefore

the answer is the option
