The angle of X is 108°
Given,
XW ≅ YZ
∠Z = 72°
then ∠X = ?
Properties of trapezoid are:
- The base sides are the only pair of sides that are parallel.
- Other than the base, the remaining sides are all non-parallel and equal in length.
- The length of the diagonals is constant.
- the same for the base angles.
We know that from the figure that ∠Z = ∠V & ∠W = ∠U
∵ Isosceles trapezoid rule
And sum of all the angles in a trapezoid = 360°
Now, 2 × 72 = 144
∴ 360 ₋ 144 = 216°
Now sum of other two angles = 216°
one angle = 216/2
= 108°
Therefore the angle of ∠X is 108°

Answer:
Step-by-step explanation:
Start by doing a much simpler problem
One
i^0 = 1
i^1 = i
i^2 = i^2 = - 1
i^3 = i^3 = (-1) * i = -i
i^4 = i^4 = (i)^2 * i^2 = -1 * -1 = 1
So now you are ready to tackle the question you were given.
Two
Every 4th power of i repeats itself. You must get one of the four answers above.
So divide 5689 by 4. What do you get?
1422.25
What does that mean?
It means that you run through the cycle of four 1422 times. What does that mean?
1 * 1 * 1 * 1 * 1 * 1 * 1 * 1 ....................................*1
There are 1422 ones in that expression.
What about the 0.25? What about that?
That means that you have one i left over.
So the answer is i
Three
The simple question defines the pattern which will repeat itself over and over again. By knowing how the simple pattern works you can develop any power of i. For example
i^15622 =
3905.5
0.5 is the same as 2/4
i^2 = -1
i^15622 = - 1
Answer:
Step-by-step explanation:
We have that, a die is rolled once.
As, the total outcomes can be 1, 2, 3, 4, 5, 6.
So, the probability to obtain 2 is 
and the probability to obtain 6 is .
Thus, the probability of rolling 2 or 6 after rolling a die once will be 
i.e. .
Hence, the probability of rolling a 2 or 6 is .
