Answer:
2/5
Step-by-step explanation:
0.4 = 4/10 which in simplest form is 2/5
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.
I would minus 2 from both sides of the equation so that it becomes:
Answer:

Step-by-step explanation:
By applying geometric mean theorem in the given right angle,

By substituting values in the given ratio,




Exact value of y is
.
Answer:
10 feet
Step-by-step explanation:
Use the volume formula, V = lwh, to solve for w
Plug in the values we know:
V = lwh
250 = (5)(w)(5)
250 = 25w
10 = w
So, the width is 10 feet
