Answers:
- Angle X = 142 degrees
- Angle Y = 142 degrees
Both angles are the same measure
===========================================================
Explanation:
We have a 5 sided polygon, so this is a pentagon.
For any pentagon, the five interior angles always add to 180(n-2) = 180(5-2) = 540 degrees. The formula 180(n-2) tells us the sum of the interior angles for any polygon with n sides.
The diagram shows the following angle values
- V = 119
- W = 47
- X = m
- Y = m
- Z = 90 (due to the square angle marker)
Both angles X and Y are equal to the same unknown value m. They are both the same measure because they both have the same arc marking.
Adding up those five angles should get us 540 as mentioned earlier
V+W+X+Y+Z = 540
119+47+m+m+90 = 540
-------
Let's solve for m
119+47+m+m+90 = 540
2m+256 = 540
2m = 540-256
2m = 284
m = 284/2
m = 142
Angle X has the measure of 142 degrees, and so does angle Y.

Answer:
(D) 9/5
Step-by-step explanation:
One way to work this problem is to find % per cup for cereal and cups per % for milk, then multiply the product of those by 2.
The way we'll use here is to find the ratio of cups of milk to cups of cereal for the same % RDA.
We're given an amount of milk that has 25% of the RDA, but we want to find an amount that has 15% RDA. That amount of milk will be ...
(15%)/(25%)(1 cup milk) = 3/5 cup milk
This tells us that 3/5 cup milk has the same %RDA as 2/3 cup cereal. That ratio is ...
milk/cereal = (3/5)/(2/3) = (3/5)(3/2) = 9/10 cup of milk per cup of cereal
Then for 2 cups of cereal, we need ...
(9/10)(2 cups cereal) = 9/5 cups milk . . . . matches choice D
Step-by-step explanation:
the answer is 6/8 = y/16
you had it right the first time rise over run is simple
the up divided by the over
rise (the y intercept ) divided by the run (the x intercept)
