<em>∠PYG = 137°</em>

Step-by-step explanation:

We know that a straight line is equal to 180°, so by looking at the image we can tell that if we added both of these angles together they would be equal to the straight line.

We can make an equation by adding these two angles together and setting them equal to 180.

2p+153+6p+91=180

We can combine like terms.

8p+244=180

Subtract 244 from both sides.

8p=-64

Divide.

<em><u>p = -8</u></em>

Now that we have found what p is equal to, we can plug it in to find the measure of ∠PYG.

2*-8+153

<em><u>= 137</u></em>

~

If you wanted to double check this answer, we can plug in -8 for p on the other side and make sure both would be equal to 180.

Like this...

6*-8+91

= 43

And we know that...

137 + 43 = 180

~

So...

<u><em>∠PYG = 137°</em></u>

<u><em>∠HYG = 43°</em></u>

I don't know if it's supposed to do with (n-2)180 <br> Also please explain :D
Sindrei [870]

Step-by-step explanation:

sum \:  of \:  interior  \\ \:  angels  \: is  \: 2340 \:  degrees. \\ (n−2)⋅180=2340 \\ 180n - 360=2340  \\ 180n = 2700 \\ n=15 \\  number \:  of \:  sides=15

the polygon is 15 sided.

 If my above assumption is correct, we can easily find the area of the left side of the rectangle by finding the area of 3 things. The first is the area of the entire region.

At = (0.8)(1.0+1.4) = 1.92

Next we need the area of the circle. Which is pi*r^2, with r being height divided by two. (0.4)
C = 0.502

Finally we need to find the area of the rectangle left region. Which is basically the rectangle from the center of the circle region to the end of the left of the entire region. This is just (1.0)(0.8) = 0.8

Finally we can find the area of the light blue area by just subtracting half the area of the circle (dark blue) from the area we just calculated.
0.8 - (0.502 / 2) = 0.549

Now for the probability we do this area divided by total area.

0.549/1.92 = 0.285 or about 0.29 which is just 29%

Please help I really need to pass this exam<br> If line GF is a midsegment of triangle CDE, find CD.
olga55 [171]
CF = FG = GC because it is equilateral triangle

So
3x + 0.8 = 2x + 3

3x–2x = 3 – 0.8

X = 2.2

Putting this value to DE

IT IS ALSO A EQUILATERAL TRIANGLE

SO
5x + 4 = 5× 2.2 +4 =

11+4 = 15

All side will be 15 of triangle CD = DC = CE = 15
