For these kind of questions unfortunately, you would have to simply memorise a list of standard trigonometry values.
Here is a link for the standard values: https://upload.wikimedia.org/wikipedia/commons/thumb/c/c9/Unit_circle_angles.svg/440px-Unit_circle_angles.svg.png
(the values in the diagram, starting from the innermost part of the circle, are 1. Angle in degrees 2. Angle in radians 3. Cosine value 4. Sine value.
In order to calculate the tangent value, take the sine value divided by the cosine value for the desired angle.
Alternatively, you could just memorise the standard values for tangent as well.
The answer to this question is 1.
