Question

ABC is right angled at C. if AC= 9 cm and BC= 12 cm, find the length AB using pythagoras theorem.​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

answer

answer 15

Step-by-step explanation:

if ∆abc is right angled

then,

if ac=9cm

bc =12 cm

find=ac?

by pythagoras theorem

(hypo)2= (side1)2+(side2) 2

then

9×9+12×12

81+1

44= √225

that is 15

ans. ab is 15 cm accurately
