Question

In a right-angled triangle ABC
with angle A = 90°, D is the foot of
the perpendicular from A to
BC. If AB=2, AC=3, then AD =______​

Answer 1

Step-by-step explanation:

By Pythagoras theorem

cb²=ac²+ab²

cb²=3²+2²

cb²=9+4

cb²=13

cb=√13

cb=3.60

Therefore, AD is 3.60

Answer 2

ANSWER:

In triangle ABC

AB² + AC² = BC² (By Bodhain-Pythagoras Theorem)

2²+3²=BC²

4+9=BC²

13=BC²

BC=3.6(approx)
