Answer:
a=69
b=133
c=116
d=93
e=86
Step-by-step explanation:
<u>first start by finding angle a:</u>
angles in a triangle add up to 180 so we can simply do 180 - 40 - 71 = 69
<u>to find b:</u>
b is on a straight line so we can do 180 - 133 = 47
<u>to find d:</u>
d is part of the small triangle on the right of the diagram, we do not know one of the angles but because it is on a straight line we can do 180-140 = 40. Now to find d we can do 180 - 47 - 40 = 93
<u>to find e:</u>
i'm assuming the large triangle containing e is isosceles so we can do 180 - 2x47 = 86
therefore c is 116 as its the only answer left - hope this helps

Answer:
Step-by-step explanation:
The work is define as the integral of the force times distance. So we have:
Now, we can write the force in terms of density.
V is the volume (V=2*1*1=2 m³)
So the work will be:
The limit of integration is between 0 and 0.5 because we want to pump half of the water out of the aquarium.
I hope it helps you!
