Answer:

Step-by-step explanation:
10 3/9 - 10 2/5
we need to convert mixed fractions to improper fractions


Now, we have 93/9 - 52/5
We need to equate the denominators, before subtracting them.




The result of 10 3/9- 10 2/5 is - 3/45
It is (c) NML
Because MN and ML is the vertex and the point meeting is M which is the angle.
The M is the angle because the common letter of both vertex is the letter M
(-2,1)
2(-2)= -4
-4 + 5 = 1
1 = 2(-2) + 5
