Answer 2

Answer:

HOPE IT HELPS U!! THEY ARE JUST SIMPLE AND BASIC QUESTION BASED ON PYTHAGORAS THEOREM!! MARK ME BRAINLIEST!!

Step-by-step explanation:

Q1) AC=100cm, BC=80cm

     USING PYTHAGORAS THEOREM;

      AC²=BC²+AB²

      100²=80²+AB²

      1000-640=AB²

      360=AB²

      AB=√360

      AB=60cm

Q2)  AB=12cm, AC=13cm

     USING PYTHAGORAS THEOREM;

      AC²=BC²+AB²

      13²=BC²+12²

      169=BC²+144

      169-144=BC²

      25=BC²

      BC=√25

      BC=5cm

Q3)AB=15cm, BC=20cm

     USING PYTHAGORAS THEOREM;

      AC²=BC²+AB²

      AC²=20²+15²

      AC²=400+225

      AC²=625

      AC=√625

      AC=25cm
