Find each angle measure.<br>​
Vitek1552 [10]

Answer for 11-13: m<2: 150, m<6: 150, m<7: 150

Step-by-step explanation:

There is 180 degrees in a straight line. If one part of the line (angle) is 30 degrees, then the other part is 150. If you look at the image, you would see that m<2 is congruent to m<6 ,which means same, and m<7 is congruent to m<3.

Answer for 14-16:  m<EBG: 150, m<AGH: 150, m<DHF: 30.

Step-by-step explanation:

4x = 150               2x + 50 = 150

x = 37.5                2x = 150 - 50

4(37.5) = 150        2x = 100

                             x = 50

                          2(50) + 50 =

                            100 + 50 = 150

I'm stuck on this question, please help. Thank you!!! ​
anastassius [24]

Let's multiply each of the four squares, one by one.

In blue, we see the dimensions are x by x.  x times x = x^2

In pink, we see the dimensions are 9 by x.  x times 9 = 9x

In green, the dimensions are x by 3.  3 times x = 3x

And finally, yellow's dimensions are 3 by 9.  3 times 9 = 27

We can now just add all these areas to find the total area:

x^2 + 12x + 27

Put the steps in order to show how to solve the equation 4y - 7 = 25
kumpel [21]

Answer:  E, A, D, C, B

Step-by-step explanation:

First, we need to get y alone. So we will add 7 to the side of the equation that has the 4y in it.

So the first one will be.

<em><u>Add 7 to both sides of the equation.</u></em>

Now the second one is

<em><u>4y = 25 + 7  </u></em>Because what you do to one side of the equation, you do to the other. So we add 7 to 25.

Then the 3rd one will be <u><em>4y = 32  </em></u>because 25+7 is equal to 32. But we still have that 4y on the other side of the equation. So the next equation is 4y = 32.

The second to last step is <em><u>Divide both sides by 4  </u></em>because thats

how you isolate y. So once you divide both sides by 4. You will get 8. Leading you into the next and final step.

<em><u>Y = 8</u></em>

And thats how you do it!
