mixed number form 6(3/4)
Answer:
We know angle AOC is a right triangle,
therefor
90 - 73 = x
Angle X is 17.
To make it easier, I am going to simplify it.
4×16-16 ? 4×[24-2×(4+8)]
64-16 ? 4×[24-2×12]
48 ? 4×[24-24]
48 ? 4×[0]
48 ? 4×0
48 ? 0
48>0
The symbol is >, so the answer is A.
r > 0 = r is greater than 0
r ≤ 8 = r is less than and equal to 8
0 ≤ r ≤ 8
