Question

In ∆ ABC,length of (AB) = 4.2 cm, length of (BC) = 5.8 cm. What should be the possible length of side AC??
(1) 1.6 cm or 10 cm
(2)1.8 cm or 9.8 cm
(3) 1.8 cm or 10 cm
(4) 1.6 cm or 9.8 cm​

Answer 1

Answer:

length of AB = 4.2

length of BC = 5.8

length of AC = ???

by pythagorize theorem

(AC)^2 = (AB)^2+(BC)^2

           =(4.2)^2+(5.8)^2

           =17. 64 + 33. 64

           =(51.28)^2

AC=  7.161
