Answer:
61.8 and 118.2
Step-by-step explanation:
Let's call one angle A and the other B. Supplementary angles add to 180, so A+B=180. If B=A+56.4, then we can rewrite the equation in terms of A, or A+(A+56.4)=180 or 2A+56.4=180. To solve, first subtract 56.4 from each side and then divide by 2 to get A=61.8. Since the angle is supplementary, all we need to do to find B is subtract A (61.8) from 180 to get B=118.2.
Answer:
Yes, her reasoning is correct
Step-by-step explanation:
Given the ratio: 109.2 : 6
Written in fractional form, we have:
Now:
Therefore, the student's reasoning is correct. In fact, as a check:
We would obtain the same result in both cases.
1/24 because you need to multiple all 3 of them.
