Question

In a triangle ABC, <ACB = 90°, AB = 30 cm, AC = 20 cm, then BC is
B. 22.36 cm​

Answer 1

Answer:

22.36cm

Step-by-step explanation:

as triangle ABC is a right angled triangle

angle ACB = 90°

AB = 30cm

AC = 20cm

and let BC = x cm

then by pythagoras theorem

hypotenuse^2 = height^2 + base^2

30^2 = 20^2 + x^2

900 = 400 + x^2

500 = x^2

x = √500

x = 22.36cm
