Question

In a right angled triangle ABC, AC = 13 and BC = 5. What is the length of side AB?

Answer 1

Answer

8

Step by step explanation

h=13(AC)

b=5(BC)

p=h-b

h2=169

b2=25

p2=169-25=144

p=√144=12*12

=12

Answer 2

Answer:

12

Step-by-step explanation:

∆abc

ac=13

bc=5

ab=?

by Pythagoras theorem

suppose

Ac=x

bc=y

ab=z

then .

y*y+z*z=x*x

25+z2=169

169-25=z*z

144=z*z

z=12

value of z means ab

ab=z=12
