Answer:

y = 100°

Step-by-step explanation:

I can't see the full question, but I'm guessing you need to find the measure of angle y.

The total angle sum of a polygon can be calculated with the formula

T = 180°(n - 2)   where T is the total angle measure, and n i the number of sides.

For our shape, there are 4 sides, so n = 4.  Plug that in and simplify...

T = 180°(4 - 2)

  T = 180°(2)

      T = 360°

We are given 3 of the angles, so angle y is

y = 360 - 107 - 104 - 49

    y = 100°

Find the midpoint of X (26,56) and Y (26,1)
Svetradugi [14.3K]

Answer:

(26, \frac{57}{2})

Step-by-step explanation:

Hi there!

We are given the coordinates (26, 56) and (26, 1)

We want to find the midpoint of these two points

The midpoint can be found using the formula (\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2}), where (x_1, y_1) & (x_2, y_2) are points

We have 2 points, which is what we need to find the midpoint, but let's label the values of the points to avoid confusion and mistakes when actually calculating

x_1=26\\y_1=56\\x_2=26\\y_2=1

Now substitute these values into the formula.

(\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2})

(\frac{26 + 26}{2} , \frac{56+ 1}{2})

Add the numbers together

(\frac{52}{2} , \frac{57}{2})

Divide

(26, \frac{57}{2})

Hope this helps!

On his way to a local Hunting and Gathering Convention, Caveperson Stony Grok picks up a rock, drops it into a lake and watches
olganol [36]

Answer:

I guess that "Ura nok seblu" means that all rocks sink in water.

Step-by-step explanation:

A conjecture is an idea, opinion, theory or hypothesis, that is based on partial or incomplete information or evidence. Conjectures are generally speculations since there is not enough proof or evidence to support them.  

Even though Stony's theory didn't have a lot of evidence to support it, he was almost right. Most rocks sink in water, I guess that the only rock that doesn't is pumice. I might be wrong, but I don't know of any other rock that floats.

5x - 22 = -7<br> someone pls help me with that
Amiraneli [1.4K]
5x-22=-7
Move -22 to the other side
Sign changes from-22 to +22
5x-22+22=-7+22
5x=-7+22
5x= 15
Divide both sides by 5 to get x by itself
5x/5= 15/5
x= 3
answer:
x= 3
