Question

construction triangle angle 90 degree ac=13cm ,ab=12 cm​

Answer 1

Step-by-step explanation:

given that angle is 90

according to Pythagoras theorem,

(x)^2=(ac)^2-(ab)^2

(x)^2=(13)^2-(12)^2

(x)^2=169-144=25

so,x=√25=5

thanks

Answer 2

Step-by-step explanation:

then the answer is bc =5 cm

explanation__ (ac)^2= (ab)^2+(bc)^2

( 13)^2 = (12)^2 +(bc)^2

169 = 144 + bc^2

169–144= bc^2

25 = bc^2

5^2 = bc^2

5 = bc

bc = 5 cm
