Answer:
Step-by-step explanation:
Cancel out 6 in both numerator and denominator.
Rationalize the denominator of by multiplying the numerator and denominator by 
.
The square of is 2
Factor 14=2 × 7. Rewrite the square root of the product 
as the product of square roots 
.
Multiply and to get 2.
Cancel out 2 and 2.

Answer:
71.6 degrees
Step-by-step explanation:
Given the vectors
u= <8,4> v = <9.-9> (5 points)
u*v = (8, 4)*(9, -9)
u*v = 8(9)+(4)(-9)
u*v = 72 - 36
u*v = 36
|u| = √8²+4²
|u| = √64+16
|u| = √80
|v| = √9²+9²
|v| = √81+81
|v| = √162
Using the formula
u*v = ||u||v| cos theta
36 = √80(√162)cos theta
36 = √12960 cos theta
cos theta = 36/√12960
cos theta = 36/113.8
cos theta = 0.3162
theta = arccos(0.3162)
theta = 71.56 degrees
Hence the angle between the given vectors to the nearest tenth of a
degree is 71.6 degrees
