Question

In triangle ABC, AD and BE are alutudes. If AD = 8 cm, BC = 12 cm and AC = 16 cm, then find BE.​

Answer 1

Answer:

BE = 6cm

Step-by-step explanation:

case 1,

ABC, b = BC = 12, h = AD = 8

A = 1/2 bh, b = = 1/2(12 * 8)

= 6*8 = 48cm²

case 2,

ABC, b = AC = 16, h = BE = ?

A = 1/2bh = 48

1/2 (16)h = 48

8h = 48

h = 6
