Answer:
A and D
Step-by-step explanation:
Parallel lines have same slope.
The ratio of the sides of a 30 60 90 triangle are 1 : sq root (3) : 2
So the sides are
7.4
7.4 * sq root (3) =

12.82
7.4 * 2 = 14.8
Perimeter = 7.4 + 12.82 + 14.8

Answer:
y=(-3/2)x+24
Step-by-step explanation:
a perpendicular line should have the negative reciprocal of the line that it is perpendicular to.
negative reciprocal of 2/3 is -3/2
out line should look something like this
y=(-3/2)x+b
then we use the given point to find b
6=(-3/2)12+b
6=-18+b
b=24
The answer is (4,5). Hope this helps
Answer:
The equation of the line is y = 4/3x - 8
Step-by-step explanation:
In order to find this, we first have to find the slope of the original line. We do this by solving for y.
3x + 4y = 20
4y = -3x + 20
y = -3/4x + 5
Now that we have the slope of -3/4 we can find the perpendicular slope. The perpendicular slope of any time is the opposite and reciprocal slope. So we flip -3/4 to get -4/3 and then we make it positive (4/3). Now that we have our new slope, we can input it along with the point into point-slope form to find the equation.
y - y1 = m(x - x1)
y - 0 = 4/3(x - 6)
y = 4/3x - 8
