Step-by-step explanation:
A+B+C=180
A+C=180-B
A+C/2=90-(B/2)
tan(A+C/2)=tan(90-B/2)
tan(A+C/2)=cotB/2
.
second answer
A,B,C are the angle
A+B+C=180
A+C=180-B
A+C/2=180-B/2
A+C/2=90-B/2
tan(A+C/2)=tan(90-B/2)
tan(A+C/2)=cotB/2.
third answer
A+B+C=180
A+C=180-B
A+C/2=180-B/2
A+C/2=180/2-B/2
A+C/2=90-B/2
tan(A+C/2)=tan(90-B/2)
tan(A+C/2)=cotB/2.
hope this helps u
all are same but in different method
