Alternate interior angles are equal, thus the given alternate interior angle is 80 degrees.
Therefore, x = 80 - 15 = 65 degrees.
Answer:
I believe its the nucleus
Step-by-step explanation:
Not entirely sure though, but its what I would pick
Table A represent a function, and Table B does not.
Why?
Table to be a function, need to satisfy following conditions (look at the .jpeg image attached with this answer):
1. condition: In first circle, EVERY element has to be connected with SOME of the elements in second circle
2. condition: In first circle, there MUSTN'T be an element that has MORE THAN ONE connection with elements in second circle
-----------------------------------------------------------------------------
Table A satisfies BOTH of these conditions; that is why table A is indeed a function.
Table B satisfies FIRST condition but it does not satisfy the SECOND condition, that is why it is NOT a function.
Let x = the height.
Then the base would be 2x - 1
The area of a parallelogram is shown by the formula
A = bh
So, plugging in for the area, the base, and the height...
91 = (2x-1) x
Now we have to solve for x.
Distribute
91 = 2x^2 - x
Set equal to 0.
0 = 2x^2 - x - 91
Now factor...
You may want to review "factoring quadratics."
The challenge is to find factors of 91 that can combine to -1 when one if multiplied by 2.
13 times 7 is 91.
If the 7 is multiplied by 2, we get 14 which is one away from the 13.
So, the factored form is...
0 = (2x + 13) (x-7)
Now to find the solutions for x, set each factor equal to 0.
2x + 13 = 0
2x = -13
x = -13 / 2
And
x - 7 = 0
x = 7
So there are two answers for x... 7 and negative 13/2
In this problem, the length of the height cannot be negative, so the only answer that makes sense is 7.
The height (x) is equal to 7.
Now, recall that the base is 2x - 1.
Since x is 7, the base is 2 (7) - 1
Or
14 - 1
Which is 13.
So the base and height are 13 and 7 respectively (in that order).
