You have 180 degrees in a triangle so 180-40-51=89
Answer:
Explanation:
Compute the magnitude:
∣∣→a∣∣=√(−10)2+62+(−7)2
∣∣→a∣∣=√100+36+49
∣∣→a∣∣=√185
To obtain the unit vector of →a=(−10,6,−7), we divide each component by √185 but we should rationalize 1√185 to √185185:
ˆa=(−10√185185,6√185185,−7√185185)

Answer ? = 9
Step-by-step explanation:
the commutative property of addition just means that when adding (say counting numbers) you can reverse the order. It won't matter how you do the addition. For example
