Question

In a triangle length of side ab, ac, bc are 3, 5, 6 cmresp. If a point d on bc is drawn such that the line ad bisects the angle a internally, then what is length of bd

Answer 1

bd is such the height of the triangle in this case
by heroine formulae
s.p=3+5+6/2
=7
√7(7-3)(7-5)(7-6)
√7×4×2×1
√7×2×2×2×1
taking 2 as comman
2√7×2
2√14
value of √14 is 3.7
h or bd=2×3.7
=7.4 cm

Answer 2

Answer:

2.25 cm.

Step-by-step explanation:

If the angle A is bisected internally, the line bisecting the angle will divide the opposite side (side BC) in the ratio of the lengths of other two sides. Therefore BC will get divided at D in the ratio of 3 : 5 (BC is of length 6 cm.)

bd=3/8*6=2.25
