Answer:
<h2>D (−4, 0)</h2>Step-by-step explanation:
The image attached shows all given coordinates. There you can observe that point D must be placed at (-4, 0) to enclose a rectangle.
We can also demonstrate this by finding that sides AD and BC are congruent.
<h3>Side AD.</h3>As you can observe, sides AD and BC are congruent. Therefore, point D must be at (-4,0), to enclose a rectangle.
Two angles are supplementary if their sum is 180 degrees.
Here we are given:
Angle GHI measures (28x + 40)° and angle JHI measures (7x)°.
Sum of angle GHI and JHI is 180.
dividing both sides by 35,
x=4
Now let us find angle JHI
angle JHI = 7x = 7*4 =28
Answer : Angle JHI is 28 degrees.
(1, -2, 1) is perpendicular/normal to the plane, and passes through the point (1, -2, 1), so its equation is
