I believe it would be 14

Answer:
C. 25%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
The new number is the increased time, 75 minutes, and the old number is the original time, 60 minutes.
percent change = (75 min - 60 min)/(60 min) * 100%
percent change = (15 min)/(60 min) * 100%
percent change = 0.25 * 100%
percent change = 25%
Since the percent change is a positive number, it is a percent increase.
The percent increase was 25%.
Answer: C. 25%
In a parallelogram, opposite angles are congruent. However, the same thing cannot be said for the other.
You can label one pair of opposite angles with x and the other 9x.
You also know that each quadrilateral has interior angles that add up to 360 so you can create the equation of
9x+9x+x+x=360
which can be simplified into
20x=360
x=18
Now, you know the angle measures of one pair of opposite angles. to find the other you plug in 18 to our other equation and multiply 9 to get 162.
The angles of the parallelogram is 18,18, 162 and 162.
Note: you can check if this is right if all the angles add up to 360.
Finally...
(1-sin x )(1+sin x )
Now we have (1-sin(x)) (1+sin(x))
There is something call Expanded which is the way to write numbers by showing the value of each digit (google)
So let's us it to see what we find.
(1-sin(x)) (1+sin(x) that's equal 1-sin²(x)
We knew that 1-sin²(x) = cos²(x)
Answer : Cos²(x)
wow I did it guys :))
Hey I hope its help XD
