Question

right time bataiye angle b is equal to 90 degree if AC is equal to 13 cm BC is equal to 5 cm find the length of AB​

Answer 1

Answer:

12cm

Step-by-step explanation:

by using Pythagoras theorem,

169=25+x^2

x^2=144

X=12

Answer 2

Answer:

12 cm

Step-by-step explanation:

AC = 13cm

BC = 5cm

AB = x

x^2 + BC^2 = AC^2 [Pythagoras Theorem]

x^2 + 5^2 = 13^2

x^2 = 169 - 25

x^2 = 144

x = √144

x = 12cm
