Answer:
yes, all of it is correct
Step-by-step explanation:
For the two triangles to be congruent, you would need the following angles and lengths to be congruent with each other.
Answer:
Yes, Emily is correct.
Step-by-step explanation:
If you have a - sign in front of a number in parenthesis that is negative, then what you are doing is taking the opposite of that negative number. Remember that the opposite of a negative number is a positive number. In this case, we want the opposite of negative five. What is that? It is +45, or 45. So yes, Emily is correct.

I used a graphing calculator to see where the two equations intersected.
Hope this helped :)
Step-by-step explanation:
You didn't provide any context so I can't answer this. BUT!!
If you're looking at two triangles, look for the side corresponding to the unknown side. If it's an equilateral (all sides same length) triangle no need to worry. It's probably a scalene, all different lengths, because math is hard. So you'll have 3 different lengthy sides, and you can probably see which ones correspond with which based on length and position. You can use angles to help you.
Now use the sides you have the value of to determine scale factor.
Divide the length of one of the sides on one triangle by the corresponding side on the other. That's your scale factor. Now multiply it by the side that corresponds to the unknown side, and that is supposed to be your length.
Sorry couldn't help any more
