Answer 1

Given data:

The given figure of the triangle.

The angle ACB is,

`\begin{gathered} \angle ACB=180^(\circ)-135^(\circ) \\ =45^(\circ) \end{gathered}`

The expression for the angle sum property is,

`\angle\text{BAC}+\angle ACB+\angle ABC=180^(\circ)`

Substitute the given and above calculated values in the expression.

`\begin{gathered} 75^(\circ)+45^(\circ)+\angle ABC=180^(\circ) \\ \angle ABC=60^(\circ) \end{gathered}`

Thus, the angle ABC is 60 degrees.
