ANSWER

EXPLANATION
Since the altitude, |GJ| bisects the base of the triangle, it follows that, the triangle is an isosceles triangle.
This implies that,.

In terms of x, we have the equation.

We now group like terms to obtain,

This implies that,

Let us divide through by 2 to get,

We can see from the diagram that,

We substitute x=5 to get,

This simplifies to,

I’m not sure this is a question and more of a statement?

Answer:
Step-by-step explanation:
You need to find “Y.”
To find “Y”, you do
-3 - 4y = 12
+3 +3
which would be -4y = 15
divide both sides by -4, and you get
y = 15/-4
Then you plug 15/-4 into “Y”, so you get -3 - 4(15/-4) = 12
then multiply, and you get -3 + 15 = 12
