If the altitudes of a triangle are `3,10,15,` then inradius of the triangle is

If length of altitudes of a triangle are 3,4 and 6 units then inradius of the triangle is,

If the sides of a triangle are xy+yz,yz+zx,zx+xy then inradius of the triangle is

If the altitudes of a triangle are in A.P,then the sides of the triangle are in

If the lengths of the sides of a triangle are in the ratio 4:5:6 and the inradius of the triangle is 3 cm, then the altitude of the triangle corresponding to the largest side as base is :

The sides of a triangle are 17 cm, 21 cm and 10 cm respectively. Find the altitude of the triangle on the longest side of the triangle

The sum of altitudes of a triangle is than the perimeter of the triangle._______
