Find the value of x that makes ABCD a parallelogram.
harkovskaia [24]

Answer:

x = 10

Step-by-step explanation:

A parallelogram's angles should all add up to 360 degrees. 130+130 is equal to 260 degrees. 360-260 is equal to 100. Because we need to find the individual angles of Angle A and Angle C, we will divide 100 by two. That leaves us with 50 degrees for Angle A and Angle C EACH. We know Angle C is equal to 5x. So, we would divide 50 by 5, which leaves us with 10 degrees. Therefore, x = 10.

Select ALL the correct answers.<br> Which of the following functions are odd? PLEASE HELP!!!! ASAP
soldier1979 [14.2K]
Odd functions are those that satisfy the condition
f(-x)=-f(x)
For example, check if x^3 is odd =>
f(x)=x^3
f(-x) = (-x)^3
-f(x)=-x^3
Since (-x)^3=-x^3, we see that f(x)=x^3 is an odd function.
In fact, polynomials which contain odd-powered terms only are odd.  (constant is even)
As an exercise, you can verify that sin(x) is odd, cos(x) is even.

On graphs, odd functions are those that resemble a 180 degree rotation.
Check with graphs of above examples.

So we identify the first graph (f(x)=-x^3) is odd (we can identify a 180 degree rotation)

Odd functions have a property that the sum of individually odd functions is 
also odd.   For example, x+x^3-6x^5 is odd, so is x+sin(x).

For the next graph, f(x)=|x+2| is not odd (nor even) because if we rotate one part of the graph, it does not coincide with another part of the graph, so it is not odd.

For the last graph, f(x)=3cos(x), it is not odd, again because if we rotate about the origin by 180 degrees, we get a different graph.  However, it is an even function because it is symmetrical about the y-axis.

How to do geometry proofs for slow students?
Likurg_2 [28]
Knowing how to write two-column geometry proofs provides a solid basis for working with theorems. Practicing these strategies will help you write geometry proofs easily in no time:

Make a game plan. Try to figure out how to get from the givens to the prove conclusion with a plain English, commonsense argument before you worry about how to write the formal, two-column proof.


Look up how to do geometry proofs and the first thing that should pop up if your on google should be a site called dummies.com
