There are 2 basic trangles used in SAT,
45-45-90
30-60-90

if you look in the attachment you will know the relationship between each so

with a  30-60-90 triangle which you have
hypotonuse=2x
hypotonuse=12
2x=12
divide by 2
x=6

I'm not sure about the  length, but I'm assuming you mean the longer side

the measure of each leg is 6 and 6 times√3




the lonnger one is 6√3
the answer is 6√3 meters

Select the equation that contains the point (3, -9), and in which the graph of the line has a positive slope.
Kamila [148]
First thing to do is to solve each of these for y.  The first one is y=-4x-3; the second one is y=4x-21; the third one is y=4x+21; the fourth one is y=-4x+3.  From that you can tell the positive slopes are found in the second and third equations.  Those are the ones we will test now for the point (3, -9).  y=-9 and x=3, so let's fill in accordingly.  The second equation filled in is -9=4(3)-21.  Does the left side equal the right when we do the math?  -9=12-21 and -9=-9.  So the second one works.  Just for the sake of completion, let's do the same with the third: -9=4(3)+21.  Does -9=12+21?  Of course it doesn't.  Our equation is the second one above, y+9=4(x-3).

What are the coordinates of the vertices of the rose garden after a translation two yards east and four yards south? Use the ter
melisa1 [442]

Answer:

The coordinates of the vertices of the original rose garden are A(3, 6), B(3, 3), C(4, 3), and D(4, 6).

Because the rose garden is translated 2 yards east (2 units in the positive x-direction) and 4 yards south (4 yards in the negative y-direction), add 2 units to the x-coordinates and -4 units to the y-coordinates of all the original vertices.

A(3, 6) will become A'[(3 + 2), (6 + (-4))], or A′(5, 2).

B(3, 3) will become B'[(3 + 2), (3 + (-4))], or B′(5, -1).

C(4, 3) will become C'[(4 + 2), (3 + (-4))], or C′(6, -1).

D(4, 6) will become D'[(4 + 2), (6 + (-4))], or D′(6, 2).
