Answer:
Q and R
Step-by-step explanation:
So lets look at the triangle.
P seems very thin, wheareas Q and R seem wider.
Normally, if given the degrees of the angles, we can subtract them from 180, which is the degrees of a full triangle, to find if two or more angles are congruent.
In this case however, we just go off of looks.
We see that angle P points strait up. This would not be the case if either Q or R where not going at the same angle, for if they were not congruent, angle P would be tilted to either the left or rihgt side.
So in the end, the best answer is Q and R.

Answer:
x=20
Step-by-step explanation:
The equation can be factored as
.. -(x -2)(x -4) = 0
The solution set is x ∈ {2, 4}.
Question?.......................
Answer:
y=5x-9
Step-by-step explanation:
<u>Step 1</u>
You are trying to get y by itself on one side, so you subtract 5x to both sides and you are left with -y=-5x+9
<u>Step 2</u>
You don't want your y to be negative (-y) and there's an imaginary -1 there so in order to make that positive you have to multiply by another -1 to both sides because a negative multiplied by a negative is a positive. Then you are left with y=5x-9 because each of those numbers were also multiplied by -1. And that's your answer!
