To find the value of x you u have to add all angles

68 + x + (x - 24) = 180

Remove parenthesis

68 + x + x - 24 = 180

Combine like terms

44 + 2x = 180

Get x on one side of the equation

44 + 2x = 180
-44 -44


2x = 136


Divide each side by 2 to isolate x


2x/2 = 136/2

x = 68


now that you have x you can put it into the equations

A = 68°

B = (x - 24)
B = (68 - 24)

B = 44°
