Question

What is the length of BC? 18 24 20 22

Answer 1

Answer:

22

Step-by-step explanation:

We have the isosceles triangle.

$AC\cong AB$

Therefore we have the equation:

$2x-24=x-2$                 add 24 to both sides

$2x-24+24=x-2+24$

$2x=x+22$              subtract x from both sides

$2x-x=x-x+22$

$\boxed{x=22}$

$BC=x$

thereofre

$BC=22$

Answer 2

Answer:

22

Step-by-step explanation:

it shows in the image that AC and AB are isosceles so 2x - 24 would be equal to x - 2

2x - 24 = x -2 ➡ x = 22
