# Many angles

Geometry Level 2

Five lines: $$l_1$$, $$l_2$$, $$1_3$$, $$l_4$$ and $$l_5$$ intersect at point O and they are intersected by five other lines $$k_1$$, $$k_2$$, $$k_3$$, $$k_4$$and $$k_5$$ (see the picture). What is the sum of the measures of the 10 shaded angles in degrees, shown in the picture below? Give your answer in degrees.
