Question

In a right angled triangle ABC, LB = 90°, BC=5 cm, AB=12 cm. Then find the length of AC.​

Answer 1

Answer:

13

Step-by-step explanation:

ABC is a triangle , in which ∠ B = 90 °

AB = 12 cm , BC = 5 cm

BC is the base of the Δ ABC

AB is the perpendicular of Δ ABC

AC is the hypotenuse of Δ ABC

We have to find AC, using Pythagoras theorem

H ² = P ² + B ²

AC ² = 12 ² + 5 ²

AC ² = 144 + 25

AC ² =  169

AC = √ 169

AC = 13
