Can someone please help me

A and B the top two

Step-by-step explanation:

3/(x - 4) = (x - 5)/x              Cross Multiply

3x = (x - 4)(x - 5)                 Remove the brackets

3x = x^2 - 5x - 4x + 20      Combine the right

3x = x^2 - 9x  + 20            Subtract 3x from both sides

0 = x^2 - 9x - 3x + 20        Combine

0 = x^2 - 12x + 20              The right side factors

(x - 10)(x - 2)

x - 10 = 0

x = 10

x - 2 = 0

x = 2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
