Answer:

BC = 24

Step-by-step explanation:

Isosceles triangle because <C = <B so AC = AB

Plug in to find x

3x - 15 = x = 33

2x = 48

 x = 24

BC = x = 24

What is the value of x in the equation x - y = 30, when y = 15?<br> O4<br> O 8<br> O 80<br> O 200
olganol [36]

\frac{1}{5}x -  \frac{2}{3} y = 30  \\

Putting the value of Y = 15

\frac{1}{5} x -  \frac{2}{3}  \times 15 = 30  \\   \frac{1}{5} x = 30  +  10 \\  \frac{1}{5} x = 40 \\ x = 5 \times 40 \\  x = 200

So, X = 200
