Question

16. In a triangle two sides are 6 cm and 8 cm then which may not be third side
(a) 5 cm (b)11 cm c) 13 cm (d) 16 cm​

Answer 1

let first side be a =6cm

let second side be b =8cm

let third side be c

a^2+b^2<c^2

(6)^2+(8)^2<c^2

36+64<c^2

100<c^2

10<c

therefore 5cm cannot be the third side (c) of the triangle
