Step-by-step explanation:
Given
We know that in a parallelogram opposite angles are equal. So
1st and 3rd angles = 118°
Let 2nd and 4th angles = x
Now
118° + 118° + x + x = 360° ( Being sum of angles of parallelogram)
236° + 2x = 360°
2x = 360° - 236°
2x = 124°
Therefore x = 62°
Now the measure of other all angles
118° , 62° , 118°, 62°
