Question

ABC triangle is a right angled at B. AB = 3cm and BC = 4cm. Length of Ac =

Answer 1

given: BC =4cm

and AB=3cm

to find:AC

Step-by-step explanation:

so,by Pythagoras theorem

a^2+b^2=c^2

AB^2+BC^2=AC^2

3^2+4^2=AC^2

9+16=AC^2

25=AC^2

AC = Squareroot of 25

AC = 5

therefore,length of AC=5

Answer 2

Answer:

(BC)™2=(AC)™2+(AB)™2

(BC)™2=4™2+3™2

(BC)=16+9

(BC)=25
