Let us make a drawing of the triangle:

Let's remember that the three angles of a triangle add up to 180 degrees. Then,

[tex]\measuredangle A+\measuredangle B+\measuredangle C=180\degree[/tex]

Since our triangle is right, we have

[tex]\measuredangle C=90\degree[/tex]

Thus

[tex]35\degree+\measuredangle B+90\degree=180\degree[/tex][tex]\measuredangle B=180\degree-90\degree-35\degree=55\degree[/tex]

This means that the answer is 55°.
