Question

if A-B-C and l(AC)=12 ,l(BC)=5 then l(AB) is ?​

Answer 1

Ans:

IF ABC IS A RIGHT ANGLED TRIANGLE AND IF AC IS THE PERPENDICULAR AND BC IS THE BASE THEN  AB =13

[BY PYTHAGORAS THEOREM]

Step-by-step explanation:

SQUARE ROOT OF (BASE^2 +PERP.^2)=  HYPOTENUSE

THEREFORE (12^2+5^2)^1/2= AB

AB=13
