Answer from: destinytofell4630

40, 60, 80

Step-by-step explanation:

The sum of angles in all triangles is 180 degrees (assuming you are talking about Euclidean geometry). If 2:3:4 is the ratio then

2x + 3x + 4x = 180

9x = 180

x = 20

Now that we now what x is, we can find the respective angles by plugging the value of x in. The angles are 40, 60, and 80 respectively.

Answer from: lindamillscotton90

40:60:80 (in accordance with 2:3:4, respectively)

Step-by-step explanation:

To solve this problem, we need to change the integers within the ratio to coefficients for new variables.

1) Convert 2:3:4 to 2x:3x:4x.

2) Add all of the variables and coefficients together (2x + 3x + 4x). We should end up with 9x in total.

3) Set the 9x equal to 180°, so 9x = 180° (180° being the number of degrees within a triangle).

4) Simplify this equation (180/9, 9x/9). We should get x = 20.

5) Substitute the x = 20 into the variables that we changed within the ratio, so 2(20):3(20):4(20). As a result, we get 40:60:80.

Since these angle measures successfully add up to 180° (40 + 60 + 80), we know we solved this problem successfully.

Answer from: Quest

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a. $y = 60(1) - 90 \\ y = 60 - 90 \\ y = - 30$ this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b. $y = 60(1) - 150 \\ y = 60 - 150 \\ y = - 90$ this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
