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.

The exradii r_(1),r_(2) and r_(3) of /_ABC are in H.P.Show that its sides a,bandc are in AP .

The exradii r_(1), r_(2), r_(3)" of "DeltaABC and in HP, show that it’s the arithmetic mean of a and c.

If in Delta ABC , sides a, b, c are in A.P. then

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

If r_(1), r_(2), r_(3) in triangle be in H.P., then the sides are :

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 24cm^(2) and its perimeter is 24cm, then the length of its largest side is 10 (b) 9 (c) 8 (d) none of these

The ex-radii of a triangle r_(1),r_(2),r_(3) are the hamonic progression ,then the sides a,b,c are
