All quadrilaterals has a total measure of angle
equal to 360 degrees. In the parallelogram ABCD, m<B = m<D = 41. So if
m<B = m<D = 41, we have 41 + 41 = 82 degrees. Since the parallelogram is
a quadrilateral, it has a total measure of angle of 360 degrees. So 360 – 82 is
equal to 278 degrees. If the measure of angle C is equal to the measure of
angle A, divide 278 by 2. We get 139 degrees. To confirm if the parallelogram
ABCD has a total measure of 360 degrees, add 41 + 41 + 139 + 139 = 360 degrees.

Answer:
5/9 m/min
Step-by-step explanation:
The depth of the water is 2/5 of the depth of the trough, so the width of the surface will be 2/5 of the width of the trough:
2/5 × 2 m = 4/5 m
Then the surface area of the water is ...
A = LW = (18 m)(4/5 m) = 14.4 m²
The rate of change of height multiplied by the area gives the rate of change of volume:
8 m³/min = (14.4 m²)(h')
h' = (8 m³/min)/(14.4 m²) = 5/9 m/min
The volume of a rectangular prism is represented by the following equation:

where w is the width , l is the length, and h is the height
Replace
with
since the length is tripled


From this, we see that this new volume is 3x larger than the original. Thus, the volume is tripled when its length is tripled.
