Question

in a right angle triangle ABC , B=90° , if AB=12cm , BC=5cm , then find AC​

Answer 1

Answer:

As per the question

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

So, the hypotenuse is 13 cm

Hypotenuse is the circumradius of triangle

Answer 2

Answer:

AC= 13cm

Step-by-step explanation:

in the right triangle ABC,
∵∠B =90° (given)
∴ By Phythororas theorem

$AC^{2} = AB^{2} + BC^{2}$
$=AC^{2} = 12^{2} + 5^{2}$
$= AC^{2} = 144 + 25$
$=AC^{2} = 169\\\\= AC =\sqrt{169} =13$
Thus, AC =13 cm
