5. A non-isosceles triangle has integral sides of 4, 5,
and x. Find all possible values of x. Solution: The triangle inequality theorem says that the sum of any two
sides must be greater than
the third side, so 5−4 < x < 4+5, or 1 < x < 9. But the sides are integral (they
are integers),
so x must belong to the set {2, ... | 677.169 | 1 |

By the hypothesis the unit vector $\frac{\vec v}{v}=: x\vec i+y\vec j+z\vec k$ make an angle $\alpha$ with the positive $x$-axis so
$$x=\frac{\vec v}{v}\cdot \vec i=\cos\alpha$$
and by the same method we find $y=\cos \beta$ and $z=\cos \gamma$ so we get $\vec v$. Finally notice that $$v=||\vec v||=v\sqrt{\c... | 677.169 | 1 |
