Triangle \(ADC\)

Angle \(D = 90\) and angle \(ACB = 45\)

So, \(45+90+ \text{angle } DAC= 180\)

Angle \(DAC = 55\)

So, angel \(ACB = 35 \Longrightarrow\) E

Solution:

Since AB is perpendicular to B, we see that triangle ABC is a right triangle with right angle at B. Therefore, angle ABC = 90 degrees. Since angle CAB is greater than 45 degrees, the third angle, angle ACB, must be less than 45 degrees. Thus, angle ACB could be 35 degrees.
