What 5 points are not coplanar with H, E, and A?
Answers
5 points that are not coplanar with H, E, and A are B, I, C, F, and G.
The figure in the given diagram is a cube. We have to find the 5 points in the cube that are not coplanar with H, E, and A.
Points are non-coplanar if they don't lie on the same plane.
From the given cube diagram, it is clear points A, E, H, J, and D lie on the same plane, while the points B, I, C, F, and G lie on a different plane. Since we have to check if the points are coplanar with respect to the given points H, E, and A.
It can be concluded that points J and D are coplanar with the given points H, E, and A as they all lie in the same plane, while the points B, I, C, F, and G are non coplanar points with respect to the given points H, E, and A as they lie on a different plane.
Therefore, using the concept of coplanar and non coplanar points, we get 5 points that are not coplanar with H, E, and A as B, I, C, F, and G.

how parallel lines change when you rotate them?
Answers
Two sets of parallel lines continue to stay equidistant to each other in each set of parallel lines, this same parallel line at an angle to the Y-axis will not intersect the parallel line at an angle to the x-axis if they are extended infinitely.
What is Angle Translation?A translation is a type of transformation that involves sliding each point in a figure the same distance in the same direction. In geometry, translating something simply means moving it around. We do not alter it in any way. When we translate a segment, it remains a segment and its length remains constant. Similarly, when we translate an angle, the angle's measure remains constant.According to the given diagram:
Although the two sets of parallel lines in each set remain equidistant to each other, the parallel line at an angle to the Y-axis will not intersect the parallel line at an angle to the x-axis if they are extended infinitely.Therefore, two sets of parallel lines continue to stay equidistant to each other in each set of parallel lines, this same parallel line at an angle to the Y-axis will not intersect the parallel line at an angle to the x-axis if they are extended infinitely.

Find the measures of the numbers angles in each rectangle
Answers
Answer:
m<1 = 60°
m<2 = 30°
m<3 = 90°
Step-by-step explanation:
Recall some properties of Rectangle. Thus:
The four angles of a rectangle are right angles = 90° each.
Opposite sides of a rectangle are also parallel to each other.
With the knowledge of these, we can solve for angles 1, 2, and 3.
Thus:
m<1 = 60° (alternate interior angles are congruent)
m<2 + m<1 = 90° (complementary angles)
m<2 + 60° = 90° (substitution)
m<2 = 30° (substraction property of equality)
m<3 = 90° (angle of a rectangle)

• Addition of integers is the process for finding out the sum of more than two variables. There may be an increase or decrease in value, depending on whether the integers are positive or negative or a mixture
• Addition in mathematics is one out of the four basic mathematical operations used for adding of two numbers.
Rules for addition of integers
• The sum of an integer and its additive inverse is 0.
• Addition of two positive integers always result in a positive value that is always greater than both the integers.
• Adding two negative values always result in a positive value what is smaller than the given numbers.
• Adding 0 to any numbers results the same number.

What is 25% of 2,000
Answers
Answer:
500
Step-by-step explanation:
= (25/100)*2000
= (25*2000)/100
= 50000/100 = 500
Step 1: In the given case Output Value is 2000.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 2000 = 100%.
Step 4: In the Same way, x = 25%.
Step 5: On dividing the pair of simple equations we got the equation as under
2000 = 100% (1).
x = 25% (2).
(2000%)/(x%) = 100/25
Step 6: Reciprocal of both sides results in the following equation
x%/2000% = 25/100
Step 7: Simplifying the above-obtained equation further will tell what is 25% of 2000
x = 500%
Therefore, 25% of 2000 is 500
