45x+angle trs = 180 straight line

angle trs = 180-45x

angle trs + angle t + angle tsr = 180 (sum of angles in a triangle =180)

(180-45x) + 25x + 57+x = 180

combine like terms

180 +57 -45x+25x+x=180

237-19x=180

subtract 237 from each side

-19x =-57

divide by -19

x=3

Find the focus. y= -1/12 (x)² - 6

jolli1 [7]

Answer:

$\Large \boxed{\sf\ \ (0,-9) \ \ }$

Step-by-step explanation:

Hello,

We know that when the parabola equation is

$y=a(x-h)^2+k$

the vertex is (h,k) and the focus is

$(h,k+\dfrac{1}{4a})$

Here, the equation is

$y=-\dfrac{1}{12}x^2-6$

$a=-\dfrac{1}{12}\\\\h = 0\\\\k =-6$

So,

$k+\dfrac{1}{4a}=-6-\dfrac{12}{4}=-6-3=-9$

Then, the focus is

$\large \boxed{\sf\ \ (0,-9) \ \ }$

I attached the graph, included the focus so that you can see it :-)

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
