Answer:
Hello! answer:
140, 140 and 40
Step-by-step explanation:
140 + 140 + 40 + 40 = 360
The other three angles would measure to 140, 140 and 40 Hope that helps!
Answer:
Answer 1.
Step-by-step explanation:
The complete question is:
The line whose equation is 3x - 5y = 4 is dilated by a scale factor of 3 centered at the origin. Which statement is correct?
1. The image of the line has the same slope as the pre-image but a different y-intercept.
2. The image of the line has the same y-intercept as the pre-image but a different slope.
3. The image of the line has the same slope and the same y-intercept as the pre-image.
4. The image of the line has a different slope and a different y-intercept from the pre-image.
Recall that a dilation by a scale factor r centered at the origin takes a point (x,y) and maps it to the point (r*x,r*y).
Consider also a line of equation
. From this equation, the slope of the line is given by the number
and the y-intercept is given by
.
Consider the given equation 3x-5y =4. If we replace (x,y) with (3x,3y), we get
![3(3x)-5(3y) = 4 = 3 (3x-5y) = 4](https://tex.z-dn.net/?f=3%283x%29-5%283y%29%20%3D%204%20%3D%203%20%283x-5y%29%20%3D%204%20)
which is equivalent to
![3x-5y = \frac{4}{3}](https://tex.z-dn.net/?f=%203x-5y%20%3D%20%5Cfrac%7B4%7D%7B3%7D)
Note that comparing the equations 3x-5y=4 and
the values of a and b are equal but the value of c is different. This means that they have the same slope but a different y-intercept.
All you do is divide.
330/390= 0.846
round it: 0.85
Answer is about 85%
Combine like terms on the left side.
-3y + 3y + 4 = 4
-3y and 3y add to 0, so you get
4 = 4
4 = 4 is a true statement, so there is an infinite number of solutions. Every real number is a solution of this equation.
Answer: Infinitely many
<1 = 123
60 + 63 = 123
180 - 123 = 57
180 n- 57 = 123
Triangle angle-sum theorem
Alternate exterior angles theorem (?)
Same side interior angles theorem
idk what the last one is about sorry
hope this helps
