Question

please answer me
it is very important ​

Answer 1

Step-by-step explanation:

let the two equal legs be x and y and hypotenuse be z

So, x^2+y^2=z^2

as x =y

x^2+x^2=98

2x^2=98

x^2=49

x=7

and so y =7

Answer 2

Answer:$(-7) or (+7)$

Step-by-step explanation:

hypotenuse square = 98

let the two sides be 'x'

by applying Pythagoras theorem,

$x^{2} +x^{2} = 98$

2$x^{2}$ = 98

$x^{2}$ = 49

x = $\sqrt{49}$

x= -7 or +7

since side of a triangle cannot be negative, the answer is +7.
