Help plz i need it very much

Answer 1

The only triangle with the base being bisected perpendicularly is an isosceles triangle or an equilateral triangle. Therefore,
`KJ = KL`

`KJ = 4x + 9\\KL = 11x - 61\\`

Since the sides are equal, we can equate the expressions to get the equation:

`4x + 9 = 11x - 61\\11x - 4x = 70\\x = 10`

`x` is equal to
`10`.

Plug that in
`11x - 61` and you get
`110 - 61` which is
`49`. So, Option B is correct :D
