" 37.If the area of the triangle "ABC" is "a^(2)-(b-c)^(2)," then its circumradius "R

If the area of the triangle ABC is a^(2)-(b-c)^(2) then its circumradius R is

Area of triangle ABC is a^(2) - (b-c)^(2) then tan A =

If the area of triangle ABC is b^(2) - (c - a)^(2) then tan B=

In the triangle ABC, if a=5, b=7 and c=3, find the angle B and the circumradius R.

AL, BM and CN are perpendicular from angular points of a triangle ABC on the opposite sides BC, CA and AB respectively. Delta is the area of triangle ABC, (r ) and R are the inradius and circumradius. Radius is the circum circle of Delta LMN is

In Delta ABC, if a=5, A=30^@ , then the circumradius is

If Delta =a^2-(b-c)^2 , is the area of the triangle ABC, then tan A=

Find the value of tan A, if area of Delta ABC is a^(2) -(b-c)^(2).
