The radii `r_(1),r_(2),r_(3)` of rescribed circles of the triangle ABC are in harmonic progression. Let area of triangle ABC be 24 and its perimeter be 24. Then which of the following is(are) correct ?

The radii r_(1), r_(2), r_(3) of the escribed circles of the triangle ABC are in H.P. If the area of the triangle is 24 cm^(2) and its perimeter is 24 cm, then the length of its largest side is

In a triangle ABC,r=

The radii r_1, r_2,r_3 of the escribed circles of the triangle A B C are in H.P. If the area of the triangle is 24 c m^2a n d its perimeter is 24cm, then the length of its largest side is 10 (b) 9 (c) 8 (d) none of these

The radii r1,r2,r3 of enscribed circles of triangle ABC are in HP . If area =24, perimeter =24cm, find a,b,c.

In triangle ABC, let b = 10, c = 10 sqrt(2) and R = 5 sqrt(2) then which of the following are correct

The sides of a triangle ABC are in the ratio 3:4:5 . If the perimeter of triangle ABC is 60, then its lengths of sides are:

In triangle ABC, r=(R )/(6) and r_(1)=7r . Then the measure of angle A =

If R and R' are the circumradii of triangles ABC and OBC, where O is the orthocenter of triangle ABC, then :

If R and R' are the circumradii of triangles ABC and OBC, where O is the orthocenter of triangle ABC, then :

The exradii r_(1), r_(2), and r_(3) " of " Delta ABC are in H.P. show that its sides a, b, and c are in A.P.
