To find the fourth angle of a trapezium, you need to know that the sum of all four angles in any quadrilateral is always 360 degrees.
In this case, you already have the measures of three angles in the trapezium as 110°, 50°, and 40°. Let's denote the fourth angle as x.
To find x, you can subtract the measures of the three given angles from 360°:
x = 360° - (110° + 50° + 40°)
x = 360° - 200°
x = 160°
Therefore, the fourth angle of the trapezium measures 160 degrees.
