In a triangle, we can relate the angles with their opposite side: the wider angle will have the largest side as opposite side.

This can be applied to the narrower angle: will have the shortest sides as opposite.

In this case, the largest side is AB, so the wider angle is at vertex C and will have a measure of 77 degrees.

In the same way, the shortest side is BC, so the narrower angle is at vertex A and will have a measure of 45 degrees.

Then, vertex B will have a measure of 58 degrees.
