Ionly need the answer for number 8 in this picture! and

Step-by-step explanation: you divide 11 by 5 because you know the length for the same side on both of those triangles therefore you divide the number for the larger figure by thesmaller one and you get you get your scale factor (the number you divide or multiply by to shrink ir stretch a figure to equal the size a similar figure). Now knowing what you scale factor is you can multiply 6 times 2.2 to get 13.2. Also you multiply 6 and 2.2 because on both triangles if you were to rotate them 6 and x are the same side of both triangles. I hope I helped.

I cant see the full picture of the bottom triangle

Step-by-step explanation:

The equation of a line that pass through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)

the find the slope

the slope of the line that passes through the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(2,0) and (0,3)
slope=(3-0)/(0-2)=3/-2=-3/2
slope=-3/2

let's do (2,0)
x1=2
y1=0
m=slope=-3/2
y-y1=m(x-x1)
y-0=-3/2(x-2)
y=-3/2(x-2)
y=(-3/2)x+3
