Step-by-step explanation:
1. draw the parallelogram with side 20cm and 25cm respectively and also the diagonal as well.
2.Clearly it forms a triangle in the parallelogram with three known lengths of side.
3.Using the cosine rule : c^2=b^2+c^2 -2bc cos c to find the obtuse angle.
X = 42 - 19, so A - x = 23
5/3 divide by 3 would be 5/9 so your answer would be C) 5/9.
5/3 * 1/3
5 * 1 over 3 * 3
5 over 3 * 3
So in total the answer would be C) 5/9.
