Question

A. B and C are interior angles of a triangle ABC. Show that
(ii) if angle A = 90°, then find the value of tan(B+C/2)


​

Answer 1

In any triangle sum of angles=180

let a, b and c be the angles

a+b+c=180

given angle a=90

b+c=90

(b+c)/2=90/2

(b+c)/2=45

Therefore

tan(b+c)/2=tan 45

tan (b+c)/2=1
