The measure of angles in a triangle are in a ratio of 2:3:4. What are the measures of the angles?
Answers
Answer:
The angle measures are 40°, 60°, and 80°.
Step-by-step explanation:
When we are given this problem, we need to know that
There are three angles in a triangle.These angles add up to equal 180°.With this ratio, these angles must add up to equal 180°. Therefore, we can set up an equation and add an x-variable to each of the numbers. We then set this equal to 180.
[tex]\text{2x + 3x + 4x = 180}\\\\\text{9x = 180}\\\\\text{x = 20}[/tex]
Now, we need to find the measures of the angles. The angles are the parts of the ratio multiplied by the value of x.
[tex]\text{2(20) = 40}\\\\\text{3(20) = 60}\\\\\text{4(20) = 80}[/tex]
So, our three angles measures should be 40°, 60°, and 80°. We can check this by adding up these three values and seeing if the sum equals 180°.
[tex]\text{40 + 60 + 80 = 180}\\\\\text{100 + 80 = 180}\\\\\text{180 = 180}[/tex]
Because this is true, our angle measures are 40°, 60°, and 80°.

d. They both have a strong assoication, but Graph 1 has a negative correlation while Graph 2 has a positive correlation
Answers
The comparison between the two graphs is that: B. they both have a positive correlation, but Graph 2 has a stronger association.
What is a positive correlation?A positive correlation refers to a terminology that describes a scenario in which two or more variables move in the same direction and are in direct proportion.
This ultimately implies that, a positive correlation exists in a graph when its variables have a linear relationship or are in direct proportion.
Based on the graphs attached in the image below, we can deduce that the two graphs both have a positive correlation, but Graph 2 has a stronger association.

The vertical line would be parallel to y- axis, hence its equation would be x= c . The slope of the vertical line is undefined, therefore there is no point slope form as such.

Find the equation of the line that contains the points (-5, 0) and (-3, 4)
Answers
Answer:
y = -1/2x - 5/2
Step-by-step explanation:
With points (-5,0) and (-3,4), we need to find the slope first.
[Find slope of points]
Using slope formula m = (Y2 - Y1) / (X2 - X1)
Using points: m = (4 - 0) / (-3 - 5) = 4/-8 = -1/2
[Use point-slope formula]
(y-y0) = m(x-x0)
Using points: (y - 0) = -1/2(x - -5)
Finally: y = -1/2x -5/2

Answer:
x= 29/11 or y= 25/11
Step-by-step explanation:
2x - y= 3 ...........equation 1
x + 5y= 14 ............equation 2
Make x the subject of the formula in equation 2
x= 14 - 5y ..............equation 3
Substitute x=14 - 5y in equation 1
2(14- 5y) - y=3
28 - 10y - y=3
Collect like terms
-10y - y=3 - 28
-11y= -25
divide both sides by coefficient of y
-11y/-11 = -25/-11
y= 25/11
Substitute y= 25/11 in equation 3
x=14 - 5(25/11)
x= 14 - 125/11
x= 29/11
Step-by-step explanation:
x= 29/11 or y= 25/11
Step-by-step explanation:
2x - y= 3 ...........equation 1
x + 5y= 14 ............equation 2
Make x the subject of the formula in equation 2
x= 14 - 5y ..............equation 3
Substitute x=14 - 5y in equation 1
2(14- 5y) - y=3
28 - 10y - y=3
Collect like terms
-10y - y=3 - 28
-11y= -25
divide both sides by coefficient of y
-11y/-11 = -25/-11
y= 25/11
Substitute y= 25/11 in equation 3
x=14 - 5(25/11)
x= 14 - 125/11
x= 29/11
