That involves very little work for me ... almost none, in fact ... because there are no angles indicated.
To find the measure of angles, first identify the angles involved. Use a protractor for direct measurements, algebraic relationships for equations, geometric properties for intersecting lines or triangles, and trigonometric ratios for right triangles. If no angles are indicated, seek clarification on which angles to address.
