undefined Solution The angle between a + c and b + c where a = [ 1 , 1 , 0 ] , b = [ 3 , 2 , 1 ] , c = [ 1 , 0 , 2 ] . The angle between a + c and b + c is 7.96 ° _ . Definition used: The angle between two nonzero vectors : The angle γ between two nonzero vectors a and b is given by cos γ = a ⋅ b | a | | b | . Length of a vector: The length of a vector a is given by | a | = a ⋅ a . Calculation: Consider the given vectors a = [ 1 , 1 , 0 ] , b = [ 3 , 2 , 1 ] , c = [ 1 , 0 , 2 ] . Substitute a = [ 1 , 1 , 0 ] , c = [ 1 , 0 , 2 ] and obtain a + c : a + c = [ 1 , 1 , 0 ] + [ 1 , 0 , 2 ] = [ 1 + 1 , 1 + 0 , 0 + 2 ] = [ 2 , 1 , 2 ] Substitute b = [ 3 , 2 , 1 ] , c = [ 1 , 0 , 2 ] and obtain b + c : b + c = [ 3 , 2 , 1 ] + [ 1 , 0 , 2 ] = [ 3 + 1 , 2 + 0 , 1 + 2 ] = [ 4 , 2 , 3 ] Substitute a + c = [ 2 , 1 , 2 ] and b + c = [ 4 , 2 , 3 ] and obtain ( a + c ) ⋅ ( b + c ) : ( a + c ) ⋅ ( b + c ) = [ 2 , 1 , 2 ] ⋅ [ 4 , 2 , 3 ] = 2 ( 4 ) + 1 ( 2 ) + 2 ( 3 ) = 8 + 2 + 6 = 16 Substitute a + c = [ 2 , 1 , 2 ] in | a + c | as, | a + c | = 2 ( 2 ) + 1 ( 1 ) + 2 ( 2 ) = 4 + 1 + 4 = 9 = 3 Substitute b + c = [ 4 , 2 , 3 ] in | b + c | as, | b + c | = 4 ( 4 ) + 2 ( 2 ) + 3 ( 3 ) = 16 + 4 + 9 = 29 Substitute ( a + c ) ⋅ ( b + c ) = 16 , | a + c | = 3 and | b + c | = 29 in cos γ = ( a + c ) ⋅ ( b + c ) | a + c | | b + c | as follows: cos γ = 16 3 ( 29 ) cos γ = 0 .99037 γ = cos − 1 ( 0 .99037 ) γ = 7.96 ° Thus, the angle between a + c and b + c is 7.96 ° _ .
