Question

Pythagoras theorem Ac^2=AB^2+BC^ ac=40 ab=20 please answer I will mark it as a brainliest​

Answer 1

Step-by-step explanation:

ac^2=ab^2+bc^2

:(40)^2=(20)^2+bc^2

:1600=400+bc^2

:bc=√1200

:bc=20√3

Answer 2

SOLUTION :

In righted angle triangle ABC

⇒(AC)^2=(AB)^2+(BC/)^2

⇒1600=400+(BC)^2

⇒(BC)^2=1600-400

⇒(BC)^2=1200

⇒(BC)=34/////////////
