Question

In ∆ABC, ∠B=90°, BD⊥AC, if AB=15cm, BD=12cm and BC=20cm then AC is *

a) 9cm
b) 25cm
c) 16cm
d) 18cm

Answer 1

Answer:

hey I think it's option option b 25

Answer 2

Answer:

AC=25

Step-by-step explanation:

abc is a right triangle

$AB^{2} +BC^{2} =AC^{2}$

$15^{2}+20^{2} =x^{2}$

$225+400=x^{2}$

$x^{2} =625$

$x=\sqrt{625}$

X=25

AC=25
