Answer:
Step-by-step explanation:
11.5 is greater than -12.5
Let the full marks be represented by = x
As given, 80% of x is 75
So,
x=
x=93.75
Hence, full marks is 93.75
We can check also- =75
12%
3 adjacent
4. complementary
x = 23
These angles are equal to each other because they're vertical angles:
2x + 1 = 47
2x = 47 - 1
2x = 46
