Math 2 Of high school

Daniel [21]

Answer:

B. BC = 18 so ∆ABC ～ ∆DEF by SAS

Step-by-step explanation:

$\bf \cfrac{AB}{DE} = \cfrac{BC}{EF}$

$\bf \cfrac{15}{10} = \cfrac{BC}{12}$
$\bf \cfrac{3}{2} = \cfrac{BC}{12}$
$\bf BC = \cfrac{3}{2} \times 12$
$\bf 3 \times 6$
$\bf BC = 18$
$\bf \angle B = \angle \: E$

So, ∆ABC ～ ∆DEF by SAS.

First we need to find the gradient of K
which is y1-y2/x1-x2
(-1,3) and (5,-2)
so it becomes 3-(-2)/-1-5
m=-5/6
when two lines are perpendicular their gradients multiply to make -1
that means the gradient of L has to be 6/5
we can substitute the point on L (5,-2) and the gradient of 6/5 into y=mx+c
-2 = (6/5) x 5 + c
c = -8
the equation of line L is y= 6x/5 -8
