It means that if u subtract idk lol
Answer:
256 i did it before
Step-by-step explanation:
B: 3 & 9
They are the smallest numbers but three still fits into both of them
Answer:
Ф=xπ, x={0,+∞}
Step-by-step explanation:
be 19cosФ=5cosФ+14 → 19cosФ-5cosФ-14 → 14cosФ-14=0 → cosФ=1
then, values for which cosФ=1 are Ф=0º=360º=720º........., but the values of Ф must be radians, so Ф=xπ, where x∈Z, not including the negative numbers,
x={0,1,2,3,....∞}
Note: π≅3.141592
when calculating the values, it must be done in radian mode
