Answer:

=94 cm

Step-by-step explanation:

Using the Triangle angle bisector theorem

We can find the value for YK

TV VY

------- = -----------

TK YK

95.2 34

------- = -----------

168 YK

Using cross products

95.2 * YK = 34* 168

Divide each side by 95.2

YK = 34* 168/95.2

YK =60

We want to find VK

VK = VY+YK

= 34+60

=94 cm

Answer:

$\frac{6+\sqrt{27} }{4-\sqrt{3} } = \frac{r+s\sqrt{3} }{13} \\We\ may\ multiply\ the\ numerator\ and\ denominator\ with\ (4+\sqrt{3} ).\\Hence,\\\frac{(6+\sqrt{27})(4+\sqrt{3}) }{13} = \frac{r+s\sqrt{3} }{13} \\Hence,\\24+6\sqrt{3} +4\sqrt{27} +9= r+s\sqrt{3}\\24+6\sqrt{3} +4*3\sqrt{3} } +9= r+s\sqrt{3}\\24+6\sqrt{3} +12\sqrt{3}+9 = r+s\sqrt{3}\\33+18\sqrt{3} = r+s\sqrt{3}\\Hence,\\r=33, s=18$
