Question

Triangle ABC is right angled at B.if AB = 5cm and BC=12 cm ..find the length of AC

Answer 1

Answer:

13cm

Step-by-step explanation:

Applying pythagorus theorem,

AC^2=AB^2+BC^2cm

AC=√(AB^2+BC^2)cm

AC=√(25+144)cm

AC=√169 cm

AC=13cm

Answer 2

13 cm

Step-by-step explanation:

By Pythagoras theorem

AC^2 = AB ^2 +BC ^2

AC = √(5^2 +12^2)

AC = √(25+144)

AC =√(169)

AC =13 cm
