Question

In ∆ABC, angle C is a right angle.a and b are the legs and c is the hypotenuse. Find the third side if: a=5, c= 13​

Answer 1

Answer:

12

Step-by-step explanation:

∆ABC is a right angled triangle

a²+b²=c²_______pythagoras theorem

(5)²+b²=(13)²

b²= 169-25

b²= 144

b= 12______taking square roots

Answer 2

Step-by-step explanation:

GIVEN,

IN ∆ABC

ANGLE C = 90°

a = 5

c = 13

NOW,

=> (c)^2 = a^2 + b^2

=> (13)^2 = (5)^2 + (b)^2

=> 169-25 = (b)^2

=> 144 = (b)^2

=> √144 = b

=> 12 = b

Hence The Third Side = 12
