Find the value of the variables. If your answer is not an integer, leave it in simplest radical form.

stepladder [879]

We know that we can use trigonometry to solve for x here.

If we use tangent, we can solve for x directly:

$tan(theta)=\frac{opposite}{adjacent}$

$tan(60)=\frac{x}{6}$

$6*tan(60)=x$

$x=6\sqrt{3}$

So therefore we have solve for x, which is D) $6\sqrt{3}$ .

What is the equation of a line that is perpendicular to 2x+3y=9 and passes through the point (8,5)

pochemuha

For
ax+by=c
slope=-a/b

perpendiculare lines have slopes that multiply to -1

so

2x+3y=9
slope=-2/3
-2/3 times what=-1
what=3/2

point slope form
the equation of a line that passes through the point (x1,y1) and the slope is m is
y-y1=m(x-x1)
slope=3/2
point i (8,5)

equation is
y-5=3/2(x-8)
converted to standard form
2y-10=3x-24
-3x+2y=-14
3x-2y=14
