Answer:
19°
Explanation:
Subtract 135 from 180 and 105 from 180 to get the interior angles of 45 and 75 on the triangle on top. Since the angles will add to 180, the third angle in the triangle is 60, which means the angle in the triangle below it is also 60 since they are opposite angles. Subtract 119 from 180 to find the second angle of this triangle, 61. This makes the third angle 59. Subtract 59 from 180 to find the angle below the 40°, which ends up being 121. Finally, add 40 and 121 together and subtract it from 180 to get the final answer, 19. :)
