I’m confused on this one
Ghella [55]

In a parallelogram, the opposite angles will be congruent to each other.


In this parallelogram, angles B and C are congruent, and angles A and D are congruent.


We will work on angles B and C first. Set the two angles to equal each other:


12x + 6 = 6x + 66


Subtract 6 from both sides:


12x = 6x + 60


Subtract 6x from both sides:


6x = 60


Divide both sides by 6 to get x by itself:


\boxed{x = 10}


x will equal 10.


Set angles A and D to equal each other:


54 = 3y


Divide both sides by 3 to get y by itself:


\boxed{y = 18}


y will equal 18.


The x and y values that make this quadrilateral a parallelogram will be x = 10, and y = 18.

Tossing a regular coin 3 times, what is the probability of getting heads every time? 4)
larisa [96]

The probability of getting heads on the first toss is  1/2 .

Then, the probability of getting heads on the second toss is  1/2 .

Then, the probability of getting heads on the third toss is  1/2 .

The probability of all three things happening is ...

                 (1/2) x (1/2) x (1/2)  =  1/8  =  0.125  =  12.5% .
