Ivan

$\bf \qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby \begin{array}{llll} k=constant\ of\\ \qquad variation \end{array}\\\\ -------------------------------\\\\ \textit{we also know that } \begin{cases} y=343\\ x=49 \end{cases}\implies 343=k49\implies \cfrac{343}{49}=k \\\\\\ 7=k\qquad therefore\qquad \boxed{y=7x} \\\\\\ \textit{when x = 8, what is \underline{y}?}\qquad y=7(8)\implies y=56$

An angle bisector of a triangle divides the opposite side of the triangle into segments 8 cm and 2 cm long. A second side of the

antiseptic1488 [7]

Bisector angle

Then apply relation

8/2 = L3 / L2

L2 = 4.9

then

8/2= 4 = L3/ 4.9

So, L3 = 4•4.9 = 19.6 cm

Also

8/2= 4= 4.9/L2

So ,L2= 4.9/4 = 1.2 cm

Then, answer is OPTION D) 19.6 cm, 1.2 cm
