Answer 1

Answer:

7cm

Step-by-step explanation:

given is an Isosceles triangle,

square of hypotenuse is 98cm .

by pythogorous theorem,

'square of the hypotenuse will be equal to the sum of the squares of the other two sides'

let the other side be x

=> x²+x² = 98

=> 2x²=98

=> x² = 98/2 = 49

=> x = √49 = 7cm
