Its impossible to draw a trapezoid with just three right angles.
a trapezoid has 4 sides, which means all the angles inside the trapezoid must add up to 360 degrees.
if you have just 3 right angles (90x3), you already use up 270 degrees. Leaving you with just 90 degrees left, which is also a right angle. That means, there has to be four, if you have at least 3.
The answer to your question is 2.4
To solve for E you'll add 867 to 108.
E - 867 = 108
E = 108 + 867
E = 975
Hope this helps :)
The point-slope form:

We have the points (5, -3) and (-2, 9). Substitute:

Just subtract 20.35 from 100.8

if your bag weighs 100.8 kg and you scoop out 20.35 kg then weigh your bag it will be 80.45 bc u took out 20.35 kg of the cement to use. hope that explains it
