Answer:
top left
Step-by-step explanation:
If you look at both equations they both have 2x in them. This makes it easier to eliminate x. To eliminate x we must subtract the second equation from the first (because 2x - 2x = 0).
So you need to use the inverse tan to find the measure of angle c.
So since tan is opposite over adjacent.
You get the inverse tan of 6/8. And you get 36.87 degrees.
Answer:
When simplified they all are 1/5
So yes they are proportional
